Start with the kit lens that comes with the camera and use it until you find it limiting in some way, then expand your lens kit to meet the need. It's more financially sound to wait until you see what you really need than to buy in advance, because if you spend the money on a lens you end up not needing, that may prevent you from buying one that will actually help.
As you expand your lens kit, consider buying used from KEH.com. Even their bargain grade lenses are in fantastic shape and reasonably priced. Let the original owner take the depreciation hit. :)
