Correct.

If I don't want the monitor powered (which I don't think I do) can I install a powered USB hub, WITHOUT the P5V connector?
Why don't you want to run the monitor off the 2140? By using the 2140 to power it, it will take care of powering it on and off along with the sleep cycle of the Mini. No worries about forgetting to turn it off or anything either.
As far as wiring, 8 gauge is the bare minimum size, but as MachineHead pointed out it also depends on the distance you have to run the cable. Poke around the FAQs for installing an amplifier as (at least wiring) this is the same thing.
Just some bits of advice:
- Don't use the type of fuse holder where the ends screw on in your engine bay. My original install used two of them and the o-rings dry rotted in a few months and made it impossible to open them without breaking them. Go with a ANL or mini-ANL fuse if possible.
- If you think you might install small to medium sized amps in the future, run 4 gauge wire into the car to where you would likely install the amps and install a 1x4g -> 4x8g distro block. Then run an 8g line to your 2140. That should make it easier to install amps in the future.
