As far as other items needing attention while the water pump is replaced.
I would say that is something the shop would have to inspect while the car is there since without looking at it, there is no way to tell.

Sounds like the car is close to a 105-k "E" service and may need that performed unless you have had all that done already.

But really it needs to be inspected by a competent shop that knows theese cars, especially one with a good engine guy that can look the car over since it sounds like you ran it hot.
