Lots of good info here.
My experience in achieving the same goal has been to:
Get a good kit. I have had some good results with premium coopers and brewcraft range.
Think about you additions of sugars / malts / maltadexrin etc. Reason being, you need to find what suits your taste. I like malty beer, but for a lager I prefer to tone the malt down a little, but you need to get the right balance that suits you. Experiment here.
Temp control is essential and I find that you need a fridge with a fridge mate so you have good control, not just using the fridge thermostat and a thermometer on your fermenter. Temps must be low, 10 - 12.
Lagering. As mentioned before a good long and low temp lager is the way to go. This becomes a challenge for fridge space!
Once temp control is available then select the yeast. Dry yeast is Ok and can give good results. My experience is SafLager was not to my taste, a little "sweet' or something, however other people tasted the beer and liked it - again preference. Dry yeast 34/70 I like and use a fair bit, it just seems a little drier on the finish.
Dry yeast is getting expensive, but can do the job. Once you get comfortable with brewing lagers with good dry yeast, get a liquid yeast, which gives you more choice and will work out cheaper when you make a number of starters.
Beware of short cuts.
At the end of all of this it is a learning curve, so keep good records and find what suits you.
