I shoot weddings and my setup is simular to yours. I use an N80 with the SB80DX flash, a 24mm, 50mm, and 85mm Nikon lenses. I think that you will do well to use your 28-105mm zoom lens with the sb80 on at all times. I use my sb80 TTL 0/0 and never worry about the exposure being wrong. I've experimented bouncing the sb80 off the attached card but haven't perfected it yet. My exposures have turned out perfect using the flash straight on and TTL at 0/0 setting, and I've shot many events with large groups of people. 400 speed film should do the trick. I generally use Fuji Superia 400. I would probably use the 18-35mm lens on the second body. That way you've got your range covered, and I find that 35mm works almost perfectly for weddings. I hope this helps. You shouldn't have a problem. Have fun with it.
