Wait with the air conditioner problem for now. It is likely to be related to the overheating.
The first issue is if the cooling system needs to be burped. Look for a bleeder screw on the thermostat housing. If there is not one, look for a plug or temperature sensor on or near the housing that can be unscrewed. If it is a sensor that you unscrew, do not turn on the ignition switch while the sensor is unplugged to prevent setting a diagnostic fault code.
If burping the system does not solve the overheating, have your mechanic perform a chemical test for a leaking cylinder head gasket.
