I'd say that you'd be better off with a DX, such as the D7100
, and the Nikon 16-85mm f/3.5-5.6G AF-S DX ED VR
. In many respects, that combination will outperform any combination of the gear you've listed. Plus, it will be smaller, lighter and cheaper. And for what you say you want to do, I don't think the 80-200/2.8 will help.
You should probably also get a good flash.
