Now we are getting somewhere.

The 70-200 with a tc or 2 is right in the budget range second hand so that leaves the wide angle.

What will be your main subject with the wide angle?
That will largely determine what will work best for you. At present the widest you will buy for an FX Nikon body is the Sigma 12-24 F/4.5 - F/5.6, you can then look at things like the Tokina 16-28 F/2.8, the Nikon 14mm F/2.8 prime or the previously mentioned Nikon zooms.
