As far as the compressor heating up, that's normal. The very act of compressing the air generates heat (canned air being released and crazy cold is the opposite). I've known compressors to get hot enough to melt hot glue. not really a specific temperature, but that's what I had laying around. If you're concerned with this high temperature melting wires or plastic, use a heatsink from a CPU on the top. Other than that, the heat won't cause any problems as it's the compressing piston heating up and not the motor.
