Very good camera. Not the greatest lens but something reasonable to get you started. At some point, you'll want additional features (faster autofocus, more wide-angle, more telephoto, brighter low-light aperture, etc.) Selecting better lenses is all about what you want to do and what budget you're prepared to spend.

If nothing else, Nikon just announced a brand new 50mm f/1.8G lens which is compatible with your camera for just north of $200. (The older f/1.8D lens requires an in-body focus motor, which your camera lacks.) That lens would be a fantastic toy for you to play with shallow depth of field, low-light photography, etc.

The other thing I'd consider getting yourself is a decent flash. The built-in flash can't do cool tricks like bounce off the ceiling.
