They say glass is the most important, which is true, but having a decent camera body is also very nice if you can afford it.
Back in the film days that was so true. A frame from a Nikon 2002 with say a 50mm f/1.8 will look exactly
the same as a frame from a Nikon F6, assuming the same lens and film are used.
With digital, the body plays a much bigger role in IQ.
The D90 is a great body, but if you can afford it, there's no reason not to get the D300s.
The prices are going back up, but if you can find a 17-55mm f/2.8 for $900 or less, grab it. It's one of if not teh
best wide-standard zoom for the DX platform. It makes a great "walk-around" lens. Personally, it doesn't leave my D300s except when I'm doing very low light video (raves, dances) and a f/1.4 lens is needed.
