Is this a sign of an overcharged unit

The Unit is a 13 year old 5 ton Trane that had the A-coil replaced about 3 years ago. First sign of a problem was the compressor wire terminal at the relay has burnt twice and then the capacitor went out. Figured I would check the amp draw on the compressor and it was 39 amps. The RLA is 29 AMPS. I also measured the fan current and it was at 1.4 amps and the RLA for it is 1.9. The measurements below were also taken.

Ambient temp = 101F
Comp discharge temp = 200F
Suction Temp = 62F


Question 1: How can the fan be checked to make sure it is turning at its rated speed and pulling the right amount of air through the condenser.

Question 2: Can the above numbers mean it is over serviced.
