What does "slow" mean? if the passenger side gets cold after five minutes and stays cold in any outdoor temps, then I would not bother with the pressures or the A/C system. I'd focus on #2, the blend door issue. Try GM forums and youtube. Find out what platform that car is, and then search for "driver not as cool as passenger XYZ platform".
