The temp at the vents should be at least 20 degrees F below ambient temp[outside temp]...it takes 2.0 lbs of 134a....may be low due to leaking compressor seal.....ask me how i know....

That'* what we leave coolers and refrigerant for! 
You should put a set of guages on that car to see what your true pressures are. Simply adding freon to a system that seems "warm" can be very dangerous if you just "put in more freon." Over charging is more dangerous than not having enough freon because the system can rupture, causing more damage, or injuring yourself.
As a side note, do you hear a clicking noise when you turn on the air conditioning? If so, does it click on and off when the car is idling? That is usually a sign that the system is low on freon (the compressor will cycle on and off to protect itself from seizing due to low freon).

If you have no freon also you will not hear it cycle at all because its been prog'd into the computer so if you do charge it you have to reset the computer by unplugging your bat. so it cycles the new freon in.
