I'm not sure that the plugged up PCV would have caused the rings to wear excessively. Maybe a little, but it is more likely that the lack of pressure ventilation from the crankcase simply blew out the seals.
Also, did you put boost on the engine around the time the oil leaks started?
I ask about boost because you mentioned installing the TB to Valve Cover hose, which is a major No-No with boost. This setup would allow boost pressure to enter the crankcase, adding to the crankcase pressure.
Running breathers on boosted setups isn't the worst you could do. Notice that the parts list for installing breathers is much shorter than the list of junk you plan to install in order to make the pcv work
