I am constantly filling the radiator with fluid. I think there is an internal leak due to white smoke from the exhaust and it kind of smells like burning coolant. I took it to a mechanic a few months ago and he put in a new thermostat. It ran well for about a month, but it's constantly overheating. When it first started, as long as the engine was reving (apprx 3000 rpm) the temp gauge would drop down to about 150. When I would let up, it would go up to 260.

Sounds like a combo of problems ...
First, like others have said, get the engine pressure tested, could either be a head gasket leak, or an intake manifold leak (between an intake port and the cooling jacket)
Also, sounds like your water pump might be getting "tired" ... as these parts get old, they get less efficient.
I'd also check to make sure your cooling fans are working, and that the air ducts under the car which direct air over the radiator are undamaged. Remember, these failed parts could just be symptoms of another issue (such as not enough cooling air passing over the radiator/engine)
Radiator cap - I saw someone mention this in another answer - a faulty cap won't hold enough pressure in the radiator to allow it to cool the system properly - it may not be the main issue, but it could be one of the issues.
Don't think of this as a bad thing, think of these broken parts as an opportunity to upgrade (heads, headers, camshaft, etc.)
**edit**
a faulty radiator cap could also cause the cooling system to build too much pressure, blowing out gaskets.

Have the cooling system pressure tested for a possible internal leak like a blown head gasket....sounds like what it is. The cooling system on those cars has to be bled of any air pockets also to prevent overheating. Pick up a service/repair manual like Chilton or Haynes at a parts store for the procedure.

check to see if the air dam is still under the frount of the car it is a strip of plastic that runs arossed the froun of your car under the bottom of the radiator if this is missing or broken the car will over heat . also check the cooling fan if it is not working it will cause the same thing to happen

Your headgaskets are blown, run a block check.
