You've had a lot of good advice here. You're giving up a lot if you go outside the Nikon CLS system. If you're on a budget, I would go with the two SB-600 route, That's what I did. Your D80 will trigger both just fine in either the iTTL or manual mode. The SB-800 does have a bit of an edge over the SB-600 but not worth the price if you're on a budget. There's nothing the SB-800 can do that the SB-600 can't do except trigger the remotes and your D80 will do that just fine.
I have two SB-600 and actually use a SU-800 (sorry to add any more confusion) to trigger them. I use this because it uses IR instead of light beams to direct the remotes, its menu is very simple and avoids using the camera's menus and it's lighter on the camera than a SB-800.
