Actually by its age all the fluides should be changed. Radiator, brakes, tranny...all of it. The Ford racing 9mm wires is the best replacement. Removing the intake manifold and cleaning the secondary ports is a must.
Plugs, wires, air filter, oil change, oil filter, fuel filter. Idk about messing with the tranny fluid, I'm one of those if its fine don't mess with it.. Flush the radiator and add new coolant.
