This is a very slippery slope you are about to begin.
Being a low mileage car that you don't track, I would say shocks should be checked and unless parts are very worn, I'd leave them.
Take it for an alignment and they will tell you if parts are within spec.
It was a great car from the start and upgrades are not really necessary.
You can change the torsion bar covers with out re-indexing the t-bars if you are careful.
Or go nuts like the rest of us.
