The oil pressure is fine. When the engine is hot, 10 psi at idle is still good, and pressure is limited to 35psi at driving speed. Nothing to worry about with the oil.
For the vacuum, that is a little low. You could cap off the vac lines going to the brakes, Choke and wipers and see if one of those is leaking more than it should.
Does altitude make a difference on vac readings? How high up are you?
Oh, and also try a second vac gauge. I also have a gauge (Stewart warner) that reads 3 inches low. You might have the same thing.
