Lawdog is right. A good book will help a lot. Also, I always recommend that people go read the current and back issues of Advanced Aquarist Online Magazine and Reefkeeping Online Magazine. They are free and have tons of good information. Some articles may be a little over your head at the beginning. Just skim them to get the general idea of what they are about and come back to them later as you get more into the more advanced stages in the hobby.
The lights I recommended will give you good color and alloew you to keep some corals, however you may not be able to get a lot of the higher light corals like Acroporas to really thrive under it. If you want to keep higher light corals, another option is metal halide lighting. You can get 175w metal halide electronic ballast kits from
www.hellolights.com for around $125 each. You would need 2 kits. Again, you would need to build your own hood for something like this. If you take shop class at school, you could probably build it there relatively easy.
As for fish, the main thing is to consider not only the compatibility of fish, but also how big they get. Many fish like tangs, large angels, groupers, etc. just get too big to keep long term in a 55g tank. Fish like blennies, gobies, Pseudochromis, pygmy angels, etc. should do well.
Keep this post going as you progress and we'll definitely help to guide you in the right direction along the way.
