Yeah, the glass is definitely going to make more of a difference in image quality than the camera, since all of the Nikon and Canon DSLRs out there are pretty good cameras. If you haven't already, go to the store and spend some time playing around with each camera. You may also want to take a look at the 50D. I know it's quite a bit more expensive, but if you like it's general design, you can pick up a used 40D or 30D for a much lower price. I got my 40D used from Adorama.com for somewhere around $700. They may be even cheaper now. The rear aperture dial and focus point joystick (they have other functions as well) were a real selling point for me. And as TitusvilleSurfer said, you're definitely going to want a good tripod. Don't skimp on that either. The cheap tripods you can get at Best Buy or someplace like that just lead to frustration. Get a nice sturdy tripod and a ball head (the tripod and ball head will be sold separate, unless you get a package deal).
