How do you say "part one, part two, part three, ect...." in spanish?
Part one. = Primera parte. Part two. = Segunda parte. Part three. = Tercera parte. Part four. = Cuarta Parte. Is this the correct way of writing it in Spanish?

You have done it correctly. In California, those who speak espanglés might do it the English way, i.e., parte uno, parte dos, etc, but that isn't correct.
