At that milage it should have had the timing belt replaced, so check for that. It is also a good idea to swap the aux belt (and tensioner) at the same time. If the aux belt breaks it will almost certainly go into the timing belt and wreck the engine. It happened to two members here last week!
Don't change the water pump (as long as it is original Volvo) unless it is leaking, which it won't be.

Normal Service Required means just that. Engine Service Required means there is a DTC.

I would change the gearbox oil. It will make a difference. Consult your manual for oil specs.

Don't forget the fuel filter. It can cause issues if it blocks.
Make sure the parking brake is working correctly.

You will love the car. Good luck
