Advice needed. A journal cap came off!

OK, here's the deal..... Car broke down last month, something pierced the oil pan, lost my oil. Shut the engine down immediately. Finally pulled the oil pan. My journal cap(between 1 and 3) came off. I guess the previous owner didn't torque it properly. So, here is my thoughts, and PLEASE all you engine gurus tell me if I am thinking right. Pull the crank, get it reground, get new bearings, reuse the rod bearings. Put the new bearings in for the crank, just torque the rod bearings. Am I thinking correctly?All advice is greatly appreciated. Thank you
