Finally some good news and a final update.
Three things were ultimately the source of the smog fail:
The new PCM seems to have been necessary, although I'm still not convinced of this. However, the downstream O2 sensor is now getting the correct voltage.
The battery light came on last week and the mechanic realized that the alternator was malfunctioning, thus causing the sensors not to receive enough voltage.
Lastly, the radiator WAS clogged up with rust and k-seal, as I had told the mechanic in the first place, and multiple times since then, but he didn't listen to me. It started running hotter than usual as he was driving it to get the sensors ready for the smog test, and only then did he conclude the radiator was an issue.
So, with the new PCM and alternator, and a flushed radiator, it is now passing smog. I'm planning to replace the radiator right away as I already have one on hand. Unfortunately, I don't have the money to pay him immediately, so it will be another week or two before I am driving it. On the bright side, he is only charging me labor for the new engine, and is not charging me labor for the other parts he tried to replace.
I hope my saga can alleviates the pain and suffering of at least one person in the future..
Thank you everyone for your continued help. Hopefully I will be back on this forum with fun updates rather than headaches.
