I like the 24-85mm lens length; Nikon has made more than one version in that zoom range. The 28-105 braineack speaks of is surprisingly GOOD on 24-MP Nikon full-frame: we shipped a 28-105 across the USA a few years ago,and I shot it on the 24-MP D3x and was happy with the image quality and focus speed.
RE: 35mm prime lens: I personally like the older 35mm f/2 AF-D lens...decent, small, nice rendering to the pictures.
Zooms: 24-70mm f/2.8 lenses...ehhhh...BIG, heavy, PITA for a lens that is not long enough at the top end to do much, and you get sharper, crisper, better images with three primes: a 24, a 35,and a 50mm. And then your real, quality lens is the 85/1.8 AF-S G.
Buy lenses that you think might suck on the used market, from a dealer that offers a money-back return option. RE: the 24-120 VR...and the used price of it...
I think the 24-85 AF-S VR-G might be the lens to buy for the D750: Nikon paired that as a kit for a while with D600 bodies...
