It all depends how far you are on the clutch's last legs. If you have worn through the friction material, you will be scraping the rivets that hold the friction material to the clutch disc across the flywheel, and if this is the case, your flywheel is toast.

With all this apart, I would swap the flywheel out, and in doing so going to a lightweight unit. I suppose if you're lucky and the original flywheel looks great, then just clean it up and take your chances, but I'm not sure I'd want to take the risk.

As to the RMS, I'm inclined to think it's better to replace it while you're looking at it- just make sure whoever installs the new seal does it correctly.
