More information than you ever wanted to know.http://www.kenrockwell.com/tech/raw.htm
In short a 10 megapixel camera is more than enough for most people who up to 16x20 prints. More megapixels will allow you to crop better after the fact for the most part. Raw is usually not "better" out of the camera because you need to post process it while with JPG you can let the camera do that for you.
This link includes mouseovers that change between jpg and NEF(raw) so you can see the difference for yourself.http://www.kenrockwell.com/nikon/d200/quality-settings.htm
