I just finished a brief search for some camera buying guides and came up with a couple of useful links for you.
CNET Digital Camera Buying Guide
There are quite a few that turn up in search results, but this one is current. And it's very comprehensive.
Digital Camera Shopping
from About.com. It's current and they also have a a second article on buying a camera plus a handy glossary.
DPReview Features Search
Once you've read the other buying guides, this one will help you find the camera that meets your needs. I've used it for real a couple of times now and it works.
