Generally you want something with the widest aperture possible for low light shooting and to control depth of field. This would indicate something like the Nikon 17-55 f/2.8DX and the 70-200 f/2.8VR.
That said, there are many wonderful pictures taken with smaller max aperture lenses.It has more to do with your skill level once you have decent (instead of great) equipment. Drfrank has shown some great wedding shots taken with the 70-300VR Nikkor. I think you need to decide how much you want to spend, then buy the best you can within your budget.
When looking at lenses for this camera, remember that the lens must have a built-in focus motor (and AF-S lens in Nikonspeak) or it will not autofocus.
