I need to know what are the necessary parts needed for a tune up for my car.

Spark plugs-get manufacturers recommended and not just the cheapest ones, dist cap, dist rotor unless is distributorless ignition-parts house can tell you, plug wires, air filter, fuel filter and pcv valve if has one that is serviceable. If you are doing this for maintenance and engine runs good then good for you. Remember that tune ups don't always fix running problems. Theoretically tunes are always suppoed to be done when running good at mileage intervals.
