You need to do the aux belt and tensioner also. These are 50,000 miles OR 5 years whichever comes sooner so you should be approaching your second change at 10 years.

It is the aux tensioner that are the Achilles heel on these engines, they fail, shread the aux belt which gets behind the guard and takes the cam belt out, result a totaled engine. Not a problem if changed as should be but I would not run them longer than recommended.

As the aux belt and tensioner have to come off to change the cam belt it should be materials only that are extra. If you have air con that belt should be changed as well. It's a one use streach fit and has to come off the pulley to remove the aux belt.
At your milage the water pump should be fine but it's always worth factoring it in the costings just in case. No point doing the job then having to strip it again shortly after to change the pump if there is any doubt.
