hi..thought i'd make up a list of things for you to look at (at your pace )
let it be known i am NO expert ! but many of these things below i was doing wrong until i came to
this site...
the info is all on this site but most of it is scattered about the place ...
hopefully these things will get you off on the right foot..
okay
[1]sanation...this link is excellent will help you understand that this is the #1 concern....

also this one

[2]fermenting tempatures: ...ales-ferment at 18-20/c is standard practice...why you ask when the
instructions under the lid say something like ?24-27/c....
well yeast is a living organism and it doesn't like to be stressed out...
at 18-20/c its all happy and happy yeast helps produce good beer...
unhappy yeast on the other hand freaks out (say when you raise the temp to 24+/c) ..
now a freaked out yeast ferments the sugars in your wort differently and produces something called a fusel ..this is a higher order alcohol that at best will make your beer taste bad and give you nasty hangovers...
now i personally ferment my ales with different yeast from the kit yeast...
[look in the wiki or your local home brew shop (lhbs) there's heaps of different strains out there]...
and i tend to ferment them on the temp range of 16-18/c...just cause i like to sure ...
you probably have one of those sticky thermometre things stuck on the outside of your fermenter..well if you do there not super accurate and by brewing at 16-18/c this way i can be resonablely sure that my brew temps will be ok...
see one of the things that happens when your yeast goes to work is that the chemical reactions it preforms
will start to create some heat...sometimes this heat is bugger all and sometimes if its really active it maybe be quite substainal say 1-2/c...(not sure on the actual amounts in degrees)
now lagers are a different story and be careful here ...
most kits contain an ale yeast not a true lager yeast no matter what the beer type says on the outside of the can ...
as mentioned two exceptions that I know of are coopers pilsner and barvarian ...these are both true lager yeasts.beware there may be others do a search or ask if in doubt/
a true lager yeast as mentioned should be fermented anywhere between 8-12/c depending on the strain..its up to you but youll probably be best off sticking to ales for your first few brews
for temp control there heaps of options more specific later (try search for temperature control and 100 can cooler)
[3] airlock activity...as you have discovered the airlocks don't always seal properly..
to fix this i use plumbers tape..that white gear for taps is about $1 or less a roll this is applied to the stem of the airlock before i sanatise it (if you don't have any use gladwrap or something)...
just apply it before you sanatise...it tends to fix the problem of leaks around the airlock...
don't freak out about the lack of bubbles the main thing to look for is the foam you've mentioned...
[4]hyrdometre use...when you want to bottle this is the way to tell if your beer is ready...
your hydrometre basically measures the density of liquids ...
the hydrometre reading of water @20/c should be 1.000 ...
to try a test on your hydrometre get some water @ 20/c immerse your hydrometre in it say half-wayish and drop and spin the hydrometre in it...
do it a few times to get the hang of it...it should settle out to be 1.000 ...
if it doesn't note the reading and use it as a calabration for your real readings...
okay as i've said your hydrometre basically measures the density of liquids ...
and a liquid with sugar dissloved in it is more dense then water thus when you make up your wort it reads higher ..a lot higher then 1.000 on your hydrometre...
(wort=the kit and the sugar mixed with water in your fermenter)
now when your yeast eats up the sugars during fermentation two of the things produced are co2 (some of the co2 leaves the liquid and some remains dissolved in it ) and alcohol...
this in turn lowers the density of the wort until it becomes beer and the yeast stop...
so when you want to bottle the trick is to use your hydrometre over the period of several days and obtain a result that is the same on 3 seperate occasions...
just note if your readings are above say 1.012 you may ...
read may have whats called a stuck fermentaion ...
a stuck fermentation is when for some reason or another the yeast has stopped doing its job even though some unfermented sugars still remain..
to fix this ,gently swirl the fermenter around until you have disturbed some of the yeast cake (that white gear at the bottom of your fermenter)...
do not swirl it violently as you want to minimise the amount of air you allow back into your wort ...though if your lid is on and airtight this shouldn't pose much problem...then leave it for the day and take another reading...
[5]bulk priming and bottling...bulk priming is just dissovling the required amount of sugar in boiling water .....then putting the dissolved sugar solution in an empty fermenter... and then racking (racking=transfering) transfering the beer you want to bottle to that same vessels as the dissolved sugar...
this is from another post i wrote but its step by step...
... but heres the go...up to you if you want to try it...but seriously theres buggerall
to it...probably best to scroll down and bring up my crappy flow chart pic when you read this
1. get your self another fermenter...
(at bunnings you can get a 25 litre camping container and a tap to fit it...make sure you get the one that
takes a tap as theres one just like it with out the threaded hole...later you can drill a hole in the lid
and then you'll have two fermenters ...above container $15 tap $2)
2.get some food grade clear hose (a couple of metres will do) that will fit over the tap
(i got mine from clark rubber...about $3)
3.always sanatize everything...
4.dissolve required amount of sugar in boiling water (say 200-250 ml)
(sugar amount from grumpys page....no copyright issues intended)

5. pour dissolved sugar into the empty fermenter
6.connect hose to original fermenter (now called #1) and place other end in the fermenter with the sugar
solution (now called #2) (make sure the hose rests on the bottom of the #2)
7. place #1 on a table or bench so it is higher then #2 (gravity will do the work for you )
8. remove airlock from #1 ... open tap and allow beer to transfer to #2 (you can whack some glad wrap over
#2 if you like to stop any nasties getting in if you like)
9.try to avoid splashing (in other words don't mix craploads on air into the liquid when you transfer it
...they tell me it can cause oxidation...)this is why you need the hose to rest on the bottom of the
fermenter.
10. the swirling motion of the transfer should mix the sugar evenly through out the transfered beer (but
if you like you can at the end give it a gentle stir with a sanatised long handled spoon)
11. now just put the lid on #2 (leave loose if you've not drilled a hole in the top of it ...so as not to
create a vaccuum when you bottle)
12.bottle
note just remember to take hydrometre readings close to 20/c ...it doesn't hurt to let you brew warm up by sitting on the bench for a day or so before your ready to bottle anyway as fermentation is clompleted anyway...
heres my crap pic flow chart below
goodluck hope its some help
cheers simpletotoro
ok heres the easiest way to explain these things above lets assume you have everything sanatisedyou got your recipe say this one for examplea really basic one
one tin of goo (ale)
500 g light dried malt (ldm)
500 dextrose
yeast from kit (ale)
ok heres how I went about it when I started..
1.put tin of unopened goo in a container pour in some boiling water to soften her up a little...set it aside till you need it ....
DO NOT BOIL UNOPENED TINS
2. put 2 litres of water in a saucepan and bring to boil
3.dissolve ldm and dextrose in saucepan constantly stirring so as not to scorch the sugar and watch for boil overs..
4.remove from heat and tip into fermenter
5.open tin of goo and tip into fermenter..mix well add a little hot water to it if you must..
6.using water you froze or cooled (in sanatised containers) fill up fermenter till desired level
7.stir the crap out of it ..you want lots of air mixed in with it lots of froath
8.check temps if its under 20/c pitch your yeaststir if you must I usually dont I just add the yeast while the liquid is still like a little whirlpool
9.bung on your lidfit you airlockferment at 16-20/c
10. watch and learn from your brew over the coming days
11.when you think it has fermented ...no airlock activity check with your hydrometer
12.bulk prime as above when ready
13.bottle
14.condition bottles for say 3 weeks then cool one down and sample if its not ready wait another week
drink as desired
lets assume youve got bugger all money or want at this stage to spend bugger all money on brewing gear there will be plenty of time later on when you have more knowledge of the art of brewing to spend money believe me
and perhaps space is limited. .
here is my advice its only advice do what you wish its your beer and hobby
for starting out controlling your fermenting temps this options pretty cheap and basic as ....collect and freeze as many 2litre soft drink bottles as you can.....
go to Harvey Norman or someone like that and get a large carborad box....big enough to fit you fermenter in with room to spare....
go to your green grocer and get some foam boxes from him 2-4 is heaps.....
get you box seal up top and bottom with heaps of heavy duty tape....take a stanly knife and cut a door in one side of it just.... cut it on three sides yeah leave the other side as a hinge..cut it big enough to get your fermenter in and out of it easily.....
line the inside with the foam boxes that you have cut up ..tape them to the sides ,bottom and top securely ....if its hot just put some frozen 2 litre bottle in the box with your fermenter .....youll have to work out what works for you best ok.....
do not stress if the temp go down below 18/c it'll just take longer for the brew to ferment out....
after some trial and error you will work out basicly how to maintain the temp in the box.....
I agree it's a pain in the arse but it does workan old fridge that doesn't work, works even better but the box is in every ones budget free
theres heaps of other stuff you can do as well ...add specialty grains ...use better yeast ...add extra hops ...without a doubt in my mind you'll end up doing these things in the future...if you want to know how...try a search or post message me and i'll give you what info i know about ok
cheers
