some top advice in here and it's great you're looking to progress.
I started with kit and kilo. I think I only did one of those though... the one that came with the coopers brew starter kit I was given as an xmas present. It was "ok" but thin and watery and cidery... I googled about beer and my eyes were opened to the awesomeness that is home brewing.
from there on all my subsequent brews were a can plus some other bits; some hops, some grains to steep, but mostly "brew improver" type things. I did a fair few "clones" from the lhbs for whatever took my fancy.
I finally decided to give all-grain a crack after I read Nick JD's "move to all grain for $30" thread when I was browsing one afternoon. I figured all-grain didn't look THAT hard. and I read that people were comparing extract brewing vs all-grain in the same way you'd compare instant coffee vs an authentic espresso machine. figured "what the hey" and got stuck in.
I use the BIAB method and only needed to buy a stockpot ($20 for a 19l from Big W) and a swiss voile curtain on top of the stuff I already had at home.
my third all-grain is fermenting at the moment, second is bottle conditioning for a few more days, and the first I'm trying not to finish drinking before the second is ready. I don't think I'll go back to kits. I love brew day. the smell of crushed malted grain is fantastic. the smell of boiling wort is great. I can't get enough of the smell of hops. and the sheer satisfaction of making it all myself from scratch is awesome. behold I are man. I make beer. huurgngngnggngnggg.
I'd definately recommend giving BIAB a bash, using the stovetop method. it's easy and it's accessible with minimal financial outlay. If you like what you produce, then you can look to going the whole hog. I'm still learning about grains and mashing and hops at the moment and BIAB lets me do simple small batches of beer to trial things til I find the beer I want to make.
check out this thread if you haven't already; it's the one that god me totally hooked and I think will ultimately be responsible for the ruin that is/was my liver.

EDIT: most of the recipes in the recipe db are all sorts of quantities, but you can download some free software such as beersmith or brewmate and use them to scale the recipe to whatever quantity/batch size you want. I use BrewMate and it's very simple to use and works for me.
