To add to what Les said, you might also want to consider replacing the cam seals and front crank seal as well as the timing belt tensioner while you're in there. It would suck to have to pull the timing belt again if any of those seals starts to leak. If the tensioner fails the belt will also fail. Then you'll have more serious problems.
