Sanity check. Does the vacuum pump hook up to A or B ?

Yep - A is ported to B when solenoid is powered - A is valved off and B is vented to atmosphere with power off

Yep - wastegate actuator should equalize within 30secs after switching off IGN, if solenoid is functional and vent screen is clear.
