I can answer some:
Water pump: It simply has a pressure switch on it: When the pressure in the system drops below a set-point the pump turns on. When the pressure goes above the set-point it turns off. Very simple.
Thus: If you leave the pump on and hook up city water: As long as the city water pressure is above the pressure switch set-point the pump won't run. The thing is: When you open a faucet the pressure in the system will drop momentarily (until either the city water backfills or the pump backfills). Typically you don't want the pump to run when connected to city water...we leave it off when connected to city water. When camping without a water hookup we'll leave the pump switch on all the time.
Cable: Yes turn off the amplifier when hooked to cable.
I don't blow out our water system (we don't notice the taste of the pink stuff and my compressor doesn't have the oomph to do the job).
