When I had my explorer done they just checked to make sure that
a. I had all of my receipts.
b. That is was repaired properly(guy said they just make sure parts aren't hanging off, etc) and was safe for the road.
c. That the horn, turn signals, lights, etc worked.
Took about 30 minutes in there and out. Hope you're not in a hurry as they're usually pretty backed up. I got lucky and the one on 40 outside of Zanesville had an opening a couple days later. They shut down though.
edit-wtf old thread haha
