On your last questions...
I'd run a 20a circuit to the fridge outlet 1st, then from this to the pump.
I'd put a reg outlet in for the fridge, you don't want a fridge on a GFCI.
At the pump you could put in a GFI outlet.
Then run another for the other outlets.
I've never been a fan of 12/2 feeding lights.....it's overkill.
That's your call.
Post some pics when your bar is done, I'd like to see it.
