My biggest surprise when going FX was that I started buying wider lens not longer. I suggest using the 300 f4 on the D7000 for birds and the 14-24 on the D800 for Landscapes.
Go to the camera store and get "Hands On" before you buy. I agree that the D600 is a better match for the D7000, but if I only had one camera it would be the D800 because it fits my hands so much better.
I used my TriPod a lot when I first got my D800, then the MonoPod. Now I mostly shoot hand held and my keeper rate has never been higher. It takes a lot of care and practice but developing technique is worth it. And, I still use that TriPod for Video.
The latest TC2.0 will work with the 300mm f4 and D800 but not with the D7000 unless there is very good light or you focus manual. My 70-200 VRI does not like any TCs. The newest version does.
