I'd be inclined to get the Zen 100mm glass Zen dome for the Tokina and the Tokina and teleconverter.
I'd also consider the macro port 60 with a 20mm extension. You can then use both the 60mm AF-S lens (with the macro port 60) and the 105mm VR lens (with macro port 60 and 20mm extension ring). This 20mm extension will be useful when using the teleconverter with the Tokina.
Let me know if you need any more help.
