Yes, that lead is very high. About 5x the average. The copper is not bad. If you haven't been using leaded race gas, you need to be concerned.
I was in roughly the same boat as you. When I bought mine, the PO had done three 15K mile oil changes. When I changed it the next time, 7800 miles later, the lead and copper were high. I have continued that oil change schedule and they have been coming down (the record of my analyses is posted above).
I'm not sure what this means relative to whether the bearings need to be replaced though. Is it a case of "the damage has been done"? Not sure.
