"You" in this case is the tech at the shop, and presumably he or she already knows how to measure rotor wear and evaluate surface condition.You should measure the rotor thickness in a couple spots and see if they are below the minimum thickness. That is typically stamped on the hat of the rotor somewhere. You can also find it in service materials for brakes. If they are below the minimum, then replace them.
If they aren't below minimum thickness, it is fine to use them for another set of pads (even if they are close to being below minimum).
If they are relatively smooth and without heavy gouges, turning them is optional, although turning them will result in better braking performance. Now, whether or not that really amounts to anything is more variable.
Brake rotors are all about surface area, and a completely flat face will have more surface area.
