The shaft (new) has a measurement of 1.122 to 1.123 , new garlock/du bushings measure 1.125 (installed ID), Joe only Jacuzzi WJ uses A large bronze tailshaft bushing/support

Neither...just a simple bushing type bearing > and there's two of them.
Thus, no need for fancy pants expensive lube > cheep-ass gear lube or even thick oil works just fine.

There are several types and maturations of these, the bushings we currenlty use resemble a cam brg of sorts but are ptfe coated

thanks in advance my BBC is ready, this weekend i'll do my first ride of the season.

assuming the bowl seal (around the shaft) holds well around your repaired shaft you should be able to fill it with 90 wt and simply periodically check it

btw not sure what the water distribution will be like given you inbound water plumbing its been my expirience water flow takes the path of least resistance and always best to have hoses equal length and simetrical may tend to run hotter (or colder)
