If by overhaul, you are referring to rebuilding it, you need a rebuild kit. If the wheels have not touched either housing, the wheels should be reusable. I might recommend finding someone else to rebuild it for you though. They are not complicated to assemble, but with parts spinning up to speeds over 100,000 RPM, I'd be reluctant to tackle that myself. It will run the same psi of boost the truck was running. You can test the pressure by adding pressure to the wastegate acuator and watching to see when the wastegate opens fully. You will need a pump of some sort with a pressure gauge so you can control the pressure and see at what pressure it responds.
As far as the wastegate, they are calibrated based on boost, not airflow.
