Amiga2000, there's no such thing as an USB video input. The hub is just that - a hub. Makes one USB connector into four.
Your A2000 will most likely be able to take advantage of the screen, but you might not have enough memory on the PIV to have lots of colours in the TFT's optimal resolution.. Check to see if you can create a display mode that's the optimal resolution of the TFT and still have at least 16bit colours. The refresh rate isn't as important with the TFT as it is with a CRT.. TFTs usually don't flicker nearly as much.
The TFT with included TV tuner probably has a better max resolution than the TFT TV with included VGA connector.. Check the specs and look for yourself.. :-)
