Nikon and canon both make great DSLR's. You will obviously hear very biased opinions from Fan boys that only own one of the brands, so don't go by that. Try the cams out for yourself and do a good amount of reasearch before investing in a body, because chances are- you may not like it and wind up upgradeing a few months later. IMO, neither D40, D40x, or D60 would be the best place to start with a Nikon DSLR, Rather a D80.
Overhead flash will be a must for aquatic photography, Sb-600, or 800.
IME i don't perticularly like to use them for anything else i shoot, being that i shoot outdoors and prefer the natural light.
Canon also Makes good entry level DSLR's, and from what i have read and heard about the newer nikon models, Canon may be a better way to go. Rebel XT's and XTI's are good entry level cams aswell, around the same price as the nikon models.
There are many many factors that come into buying DSLR's and equipment when you get down to it, so you'll have to do a good amount of reaseach before decideing to buy the first one you see in your price range.
kenrockwell.com as stated is a good place to start, but there are many other websites with up to date reveiws on the newest cams for sale.
