Hey thanks all. I checked the low pressure side and it actually reads 45 psi w/compressor on and 60 psi w/ system off. Which is actually pretty good. So I did'nt recharge it. It might have a very small leak but I have'nt recharged it in a long time.
As far as the oil residue by the clutch maybe that's where it's leaking out oh so slowly through the seal. Could low oil cause the compressor to cycle off too much or cause the system to lose coldness? If so, should I charge my system up with one of those that pag oil recharge cans from Napa? They have one there that's made for my truck that also has ring and seal conditioners that can prevent leakage. Could that help?
