You have a bunch of completely unrelated problems. First you have to determine where the coolant is leaking from, assuming it even is coolant. Some newer coolants are red but so is automatic transmission fluid.
The resistor has nothing to do with a leak. Sometimes they overheat and burn open when the heater fan becomes tight and draws excessive current.
What was the symptom that required replacement of the manifold? Intake manifold I assume? That would have nothing to do with a coolant leak. Same for a spring-loaded tensioner pulley. That's a mechanical part that holds the serpentine belt tight. There is nothing to leak related to that part.
If the water pump is indeed leaking, $300.00 seems a little high for a 3.3L engine. You should be able to see that leakage yourself from underneath but it is kind of hidden by a plastic splash shield at the right front corner of the engine bay. If you have the 3.0L engine, $300.00 is too low for replacing the water pump. That one involves removing the timing belt, but those pumps don't leak or fail very often.
