One valve has a clear hose that connects to nothing, it was open and as I started filling the tank with water, water started coming out of it so I closed it. I assume this is some kind of vent? When should this be open and closed?
It's for winterizing - just turn the valve so it's open, stick the hose in a jug of antifreeze, turn on the pump, and it will run antifreeze through the water system.

The other is in line with the hose that connects to the bottom outlet on the tank, I assume you close this valve so the tank doesn't fill with water when you are connected to city water? And of course open it when you are using tank water?
In most cases when the winterizing valve is open it also closes the draw tube from your fresh water tank - without pics (can't see yours) it's hard to tell but I'd suspect this second valve does just that - close it for winterizing but open it for the rest of the season. The pump itself has a check valve to prevent city water from entering the tank so another shouldn't be necessary.
