Could I adjust the pressure electrically (e.g. by putting a resistor between the power supply and the pump) or is a physical valve the only option?

Yes you can adjust the speed as I have a motor speed controller attached for my application.

If i reverse the polarity, can this be used to pump instead of suck? I have a........thing........and she needs inflating. Then i can flip the polarit

Unlikely. Whether the unit is a vacuum pump or a pressure pump will depend on the internal valve arrangement which I doubt can be changed.
