So you don't have any repair history? During the valve stem seal replacement you should get the timing covers and valve cover gaskets replaced (and a bunch of O-rings and such).

Oil cooler t-stat gasket is another biggie.

You're lower mileage than me but I recently had to do a coolant system refresh. Coolant transfer pipe is another possible repair coming up.

Rear air bags (if you have them) tend to last 8-10 years.

Frankly the list could be endless. The important part in determining what you might need to DO, is what has been DONE.
