Ok, so everyone has suggested google, shows, breeders, vets, and books. All excellent suggestions. I will add, DO NOT go on the advice of anyone at a pet store. While they are all well intentioned I'm sure, please remember most of them deal with cats and dogs and are college students (it's a generalization not trying to offend anyone who works in a pet store). There are times when you will find someone that actually knows what they are talking about but that would be the exception not the rule.
That said, I will offer up my own advice. There are a few questions to answer before you actually get your rabbit. (Well, tons really but these will help with your research.)
1) Is your rabbit going to be indoors or out? Very different housing requirements for each of these.
2) What are you getting one for, just a pet or for meat?
3) How big are you wanting your rabbit to be?
4) What type of personality would you like? (Do you want a big, floppy love bug or small and more of a 'just pet me' pet?)
Food requirements are pretty straightforward as far as the minimum is concerned. Good quality pellets and some variety of grass hay. I feed mine Purina Rabbit Chow (just switched to that one and they seem to like it better) and timothy hay. Some people only feed pellets once a day but I believe in the "free feed" system for all my animals so they have pellets and hay available all the time. Rabbits love treats but you want to make sure they are the right kind. I posted a treat list a while back, this is the thread for it -

As for housing, rabbits need lots of exercise so the more space the better. If you want your rabbit inside a C&C cage is the cheapest (and certainly one of the best) way to go. This site explains what a C&C cage is and how to make one, they started out for guinea pigs but they work very well for all other kinds of small animals.

However, leaving a rabbit unsupervised is not a good idea unless you've completely rabbit proofed the room. They will chew any wire they can get to. If you go with the outside option, they still need playtime so they can run around a bit. Outdoor hutches vary tremendously, the pet store ones are really expensive but easy. If you're handy with tools, you can make a larger/better one for less than that.
One of the main things to know about rabbits is that they are territorial. That's not to say they won't get along with another rabbit (especially if they are raised together) but they don't need a buddy if they have enough interaction with you. If you do end up with more than one, they each need their own cage and if they are fixed (don't want more rabbits) they can be let out for floor time together. Even unspayed females can have problems with each other.
Ok, so the last piece of knowledge I will pass on is that they do very well in the cold but can succumb to heatstroke when the temps get high. Frozen water bottles (2L or Gal) work very well to keep them cooler, they will lay against the bottle to keep their temp down.
Good luck! If you learn as much as you can before you get your rabbit, you will be much happier and less surprised by something later on. And, of course, post pictures when you end up getting it!
