The pricing I don't get at all, but I don't think it's a grey-market lens in the kit. I think someone at B&H just used the wrong link.
As to the particular kit-lens selection, I don't see that Nikon had a lot of choice (other than to not offer the kit at all). Kit lenses are generally wide-to-short-tele zooms, and the 24-120 is the only modern (AF-S, VR) non-DX design Nikon has available at present except for the f/2.8 glass. (A lack they will no doubt correct at some point.)
The inclusion of NX with the D3 and D300 was a temporary, one-shot deal. Capture wasn't included with the D2X, and I wouldn't expect it to be included with future bodies. You can use View NX to process D700 RAW images, so it's not as if you have no access to "the best images the D700 can produce."
