I was assuming he already had racking equipment since he does one gallon batches however if you dont, you need it and I agree with ludomonster about the autosiphon unless you really like the taste of green beer (which I kinda do)
As for when it comes to the fermentation chamber I currently hold nothing on that. My basement stays at a constant 70F for summer so its a little hot for some yeast but it hasnt failed me yet. I am probably going to invest in a big tote full of water and put frozen water bottles in it every morning. So you can go fancy or you can go shmancy depending on your budget. I am cleaning up my one gallon equipment however to start experimenting with lagers by putting them in my basement fridge.
Joe, what I would really suggest for getting your first equipment kit is look into all your options. Midwest Supplies, Northern Brewer, Morebeer, Adventures in Homebrewing, Austin Homebrew supply, you name it. Youre going to find that each kit is very similarly priced and you get about the same stuff packaged under different names. Certain people like one brand versus the other but it all does the same thing. You just have to decide what you want to start with. If you have the extra money go with a full blown kit that will either allow you to keg or do all grain batches. If you dont, I have seen kits for as low as $70 that will get the job done.
