Siphoning with your mouth is a bad idea...I tried it with one of my first batches and ended up with a very plasticy off-flavor....It runs a very high risk of contaminating your beer and also oxidizing it, which are two things you don't want.
You would need to get a temp controller for the fridge. Good chance that is more expensive than you would want to spend. Around $75. If you keep it around 68 it should be ok.
