I'd wait on the pitot-static check until after the annual. You may
find lots of hoses and tubing that needs to be repaired/replaced which
requires another pitot-static check, wasting $200-300.

In fact, I'd wait until after the annual to do anything. The
annual should provide the "shopping list" what needs to be
replaced/repaired.

As for what should be done...do you have the checklist from
Piper (in the maintenance manual, table III-I, Inspection Report).
That will be the starting point. You may want to have each item
on the seven pages evaluated.

Who's doing it? Someone at BJC?
