Change your thermostat and rear brakeshoes.

If you are getting white smoke when you start it, one of your coolant seals has let go and you'll need to tear the motor apart to fix it.
Don't let it get too hot or you'll warp stuff in the engine.

Sigh.

Overheating: http://www.aaroncake.net/rx-7/cooling.htm

Parking brake light: First, resolder the instrument cluster light (search for info). Then, adjust the parking brake lever (see instructions in Haynes manual). The rear pads have nothing to do with it, and since 2nd gens don't have drum brakes, we have NO brake "shoes".

AaronCake has it right on the parking brake light. If it is not a bad solder joint at the back of the gauge cluster then it is bad solder joints in the ECU down by your feet on the drivers side. The overheating problem is deadly though. That could be a number of things, mostly all of them would point to a rebuild. If you can not locate a leak then it sounds like it could be a coolant seal in the motor. If it is that you should smell/see coolant in the exhaust.

Wait! The parking brake light also comes on when the brake fluid level is low. Check that first.

Yes, check your brake fluid first. My light stayed on yesterday after I let my p-brake go. My brake fluid was low, and I just had to refill it. Light went off.
