Have you replaced the radiator cap? If this fails to hold at specified pressure it could overheat. If you are losing coolant and it is not visibly leaking anywhere it certainly could be a bad head gasket. With no coolant loss, it could be a faulty temp guage (unlikely) or a faulty fan clutch which looks like it's working but actually isn't pulling enough air through the rad to cool it. As far as cabin heat, have you ever changed the cabin air filters? There are 2 behind the glove box. Is the temp low or the volume of air flow low? If it is the volume, it most likely is clogged cabin filters. If the temp is low it may be a faulty control valve not allowing enough hot coolant into the heater core. Good luck!
