If you are able to match the caliper, pads, and rotor at each corner the way the previous owner was running them and he had no issues with vibrations, you can throw them on.

Otherwise, I would at least re-bed them. Do you plan to track? Pick up some track pads and run them for a few days to clean up the rotors. Then re-bed the street pads.
