Like Ed said, drop the drag link, jack the engine up some, pull the pan, clean it really well, throw away the old pump and pickup, replace them, and replace the pump drive with a hardened tip and bevelled transition.
While the pan is off, it might not be a bad idea to pull a front cap off of one of the connecting rods and one off of #1 main to inpect the bearings and see if you did more damage than you think. It's better than throwing it back together and having problems a little down the road.
