+1 on all of the above as this car is pretty good at keeping itself together so to speak!
Check out the videos on YouTube for the caliper pin greasing as it is not super technical but if unsure then any Indy garage worth its salt should be able to do it with their eyes closed, just check they ain't using Copper Grease!
As for the water pump, yes they don't last for ever but changing one out that ain't faulty doesn't sit right with me, when they do start to fail there is usually a tell-tell staining of pink ( from the coolant) under the shaft area on the aluminium casing, so if you check around here on a regular basis you will spot a failing pump early before it fails catastrophically.
one maintainance job that can be done very easily is the MAF sensor cleaning, check that also on the toob!
