He's talking about the amperage DRAW of that particular starter. If your charging system is in good order and the battery is fine, I wouldn't worry about it. Basically, if it draws rediculously high amps it's because the winding in the starter motor is all fawked up. I've personally never seen a Toyota starter fail due to bad windings or excessive amperage draw. Just about the only thing that ever goes out is the contacts and plunger. If you install the new contacts nice and straight and polish the contact surface of the plunger, it'll be fine.
I seem to remember you can flip the contacts over to get a clean surface. Am I wrong?
No, you can't flip the contacs as they only go in one way and they're "L" shaped. They only really wear on one side, but can't be flipped.
