The Nikon kit lenses are pretty good, 18-55 vr, 55-200vr, especially for the price, as used they are dirt cheap and they're plenty sharp if you stop down a bit. Next step up is a fast zoom, 17-50 (non vc Tamron) is excellent, if you can find one, and gives a low light option. For a basic set up I'd look for the Tamron and a fast macro lens, a 2.8 90-100mm that'll double as a short tele. Alternatively the Nikon 18-105 would give you a single lens option for travel. Good luck, lots of choices out there.
