Slow down... pick up your local yellow pages, and look up "Photography equipment" or "Cameras, retail" and pick three or four shops that you can get to easily. Visit each one, explain to the sales-person what you want, what your interests are, and what your budget is. They will show you the model(s) they have, and give you recommendations. You may well find that you like one model over another simply because of the way it feels in your hands. Yes, Nikon and Canon are both top names, but don't forget about Sony, and Pentax. As well, there's always used equipment to consider.
Most entry-level DSLRs are available as kits with one or two lenses included in the price; these are generally mid-range zooms which are suitable for a wide range of basic photography.
