the 18-105VR is reasonable. Coupled with (old) 60mm 2.8a and 50mm 1.4 & the 70-300
The elephant in the room is "what is your second camera" I shoot a combination of 2 FF an 1 crop, so the lenses I use need to work on all cameras I shoot with
The D7000 is a competent camera, but I would never walk into any job (esp. weddings) with one camera. I find D7000's soft on focus (you really need to fine tune a lens on it). Saying that while I normally shoot a D3s (x2) I use a D7000 to flex the lens options. A D7000 is my first choice of camera to go running out of the door with (personal stuff) . On a D7000, the 18-105 VR is a very good all-round lens choice. Yes it has problems, but most of them are fixable in PP. If you are equipment challenged, it is a good replacement for a "kit lens". As I said, for anything unimportant, I run out the door with a D7000 and a 18-105VR, and as a standalone set up, it is pretty damn good
