Justin,
I don't think he will ever be happy with the AC and the generator. Generators don't put out much if anything at idle no matter what the rating is. You could convert to an alternator and use a later model pump for the PS. Several of the aftermarket guys have a pump bracket that replaces the LF motor mount. You have to reduce the pressure in the newer pumps and probably run new lines and add a pulley . The car is not stock now with the aftermarket AC so might as well upgrade it to make it more driveable.
