I agree with the timing when replacing the clutch. If you have the whole thing pulled apart anyway, why not spend the extra dollars for the update? I wouldn't do it before then, unless you're paranoid.

Do change your oil at least every 5k miles...that will do a lot to help keep the engine healthy and minimize wear on all the weak components...and consider 5W or 10W40; not 0W40.
