I don't think all those things are related. For the brake light thing, check the brake fluid level. It sounds like the fluid is swishing around causing the float switch to turn off and on.
As for your overheating and timing belt problem, stop driving it immediately. You may have a water pump or something letting go but this is an interference engine so if it jumps time while your driving it, it could bend all the valves.
