A subject near and dear to my heart -- I've been a homebrewer for 13 years.
I recommend this site:
http://howtobrew.com/
The author wrote a homebrewing book, but ended up making just about all of the info in it available on his web site for free. It's got great "beginner" material on brewing your first beer, but it's a good source of information for advanced brewers as well.
I'd also suggest looking for a local homebrew club, which can give you a chance to ask questions and sample beers from other, more experienced brewers.
Good luck -- poker and homebrewing are two very compatible hobbies...
