Not sure what your budget looks like, but you need to consider a "full room" UPS.
Typically, they will have multiple circuit inputs, for redundancy, and then you run your power around the room, like normal. The down side would be typical. (Often a rack unto themselves)
I would definitely plan for 40% over current and / or expansion.
If full-room is not in the cards, APC and generator Tripp-Lite both make some very fine UPSes.
