What does the D300 bring you? It is almost the same weight as the D700, so it is not a weight advantage. Not sure what is your aim...
What APS-C brings you is more tele reach for images.
You already have the Tamron 70-300 f4-5.6, so on APS-C: what does a Tokina 50-135 bring you, really? Not anything the Tamron 70-300 and Nikon 70-200 already bring. If it is weight, the Tamron is the tool to use, if it is f2.8 the Nikon is it. So, why the Tokina? Tele reach is the APS-C advantage, and the Tamron gives you that.
Then the Nikon 300mm f4. Why that lens? You already have a Tamron 70-300 VR, which gives the 300mm f4 a run for its money and sharpness. Is the step of f5.6 to f4 at that focal length really something you should concern yourself with? And you have that 70-200mm VR then too... Adding a 1.4x TC from Nikon or Kenko also get you about 300mm f4.
Seems to me (but, I can be wrong, hence I am asking what it will bring you) that you are making redundant choices.
I think the following makes more sense:
Get a light good standard travel lens for the D300s. Like the SIgma 17-50mm f2.8 EX DC OS HSM (lovely lens). That makes it a lighter, bit more compact kit, combined with the Tamron 70-300mm a great combination to travel lighter with than the D700 24-70 f2.8 + 70-200mm f2.8.
Then combine it with 2 light primes, that may or may not also serve well on full frame:
A 30-35mm one, for standard view and more compact and light than the 17-50mm f2.8, like the APS-C lenses Sigma 30mm f1.4 EX DC HSM, Nikon 35mm f1,8 DX, or the FF lens Nikon 35mm f2. And then a Nikon 85mm f1.8, for long portrait lens on APS-C and moderate portrait lens on full frame. It is a lovely lens to have.
