I used to have the D50 with kit lens and a 70-300G lens. When I got the 18-200 vr lens, it was the only lenses on the body as there is no further need to change lenses anymore, except for a 50mm f1.8 or the Tokina 12-24 for t low light and UWA.
It would depend on your shooting style and what you need to determine which lenses to get.
