My question concerns the PCM: is this a new module that can be swaped for the old by the "un-plug/re-plug" technique, or do we have to remove and replace chips?
The Injectors and gaskets are a slam dunk though.

Kirby,
The PCM should be replaced as a unit, from my understanding. After removing Negative battery cable it would be a matter of clearing a path (clutch slave cylinder and/or other items mounted to the PCM bracket) unplugging 3 or 4 connectors (3 for the Manual trans, 4 for the auto trans), unbolting the PCM bracket, unbolting the PCM from the bracket, mounting the new pcm to the bracket, and mounting the bracket to the firewall. Then replace standard obstacles, reconnect negative cable and back in business.
I think some of the "chip" manufacturers install internal "piggyback" circuit boards that parallel additional processing to the original ROM, EPROM or EEPROM in the PCU, but I don't think that Mopar is counting on this being done at the customer or dealer level.
