Even if the belts look good, they get hard & slippery with age & heat. Then you have to over-tighten them to stop them from squeaking. That's hard on the bearings. I'd wait till the belts squeak, because they're easy to change whenever needed.

Lots of people replace the waterpump along with the timing belt, since it's not likely to last another 90k miles. Your timing belt has to come back off to do the waterpump, but it's too late to do all that together.

Again, I'd wait for the waterpump to leak. It's too late to do it together with the timing belt. Waterpumps rarely go quickly. They either begin leaking slowly or they start making noise. If it goes another 40k miles, then do the waterpump & timing belt together at that time.

Valve clearance & spark plugs are up on top where they're easy to do by themselves. It's not real important that those jobs be combined with the belts.
