Does anyone know how to check for problems with my brake booster? I think I'm having some vaccuum probs. Thanks

A good test is to see if the idle changes at all when you press the brake pedal down while in park or neutral. If the idle changes, then that's a good sign you have a leak.

I lose clutch pressure and brake pressure sometimes. Sound like a leak?? And I stall after hard driving when I push in the clutch.

It sounds like you might need to bleed both systems. You might have air in the lines. As you drive, the air heats up and expands, which would explain any softness in the pedals.
