Well, the Nikon D80 can shoot 3 frames per second, while the Nikon D200 can shoot 5 frames per second.
On the other hand, the speed of the auto-focus depends on the lens itself. The "AF-S" type of lens have a fast internal motor, which I would assume (although I'm not completely sure) auto-focuses faster than those for which the internal motor of the camera body is used.
To shoot fast moving subjects at long distances, such as planes, you will need a fast telephoto. Vibration reduction won't help, as it simply won't be enough time for VR to start making effect before your subject moves away (but high end telephotos will have VR, anyway). The downsides are high price and low availability. I guess you could do worst than the Nikkor AF-S VR Nikkor 300mm f/2.8G IF-ED
. If you're willing to spend well over USD 4500.
But then, you will want VR for other occasions. Also, a zoom is more flexible. A high quality zoom, that has VR, but is not particularly fast at the longer end is the Nikkor AF-S DX VR 18-200mm 3.5-5.6G IF-ED
