Existing 220 wiring. Will it work? Pics inside.

No real reason to stress about running 120v items off the 220 then just run a spare 120 into your controller box for pumps.

Use that line for 30A 240V then use the 120V source in the garage for pumps/control power. There is no reason not to run both into your control panel. I feed into my control panel(s) with three separate circuits.

Can I run the black and white as hots, and the bare as neutral?

No. Not with that type of cable and not with that type of circuit.

He mentioned running this outlet through a spa panel in the OP, wouldn't that allow him to have 4 lines coming out and draw the 120 off one of the hot legs and the new neutral?

NO. A spa panel does NOT create anything new going out vs. what's coming in with regard to wire functions.

That's a great idea. Unfortunately as you can see from this thread, I'm pretty clueless with electricity. Hence the reason I was looking at buying one. Are there any existing schematics for my situation?

Sorry, I missed your reference to the prefab unit. I can't point you to a specific schematic but if you find one that fits your general plan, it could certainly be modified to fit the power you have available.
