Question: I want to confirm that the hot side of the wall power line connection goes to the side of the Bakelite cap with the .10uf cap that goes onward via a red wire to the on/off switch, and that the ground should attach to the Bakelite cap where the black wire running to the power transformer goes.
When re-wiring the set to get rid of flaking wire, I already found some wiring colors that weren't right (red wire used on an obvious ground lug connection) and I want to be sure.

There isn't any point in installing a polarized plug on an AC set, thanks to the transformer the chassis is alreay isolated from the power line. What I would do is change the electrical orientation of the line capacitor, reconnect it so one side of the cap is connected to the radio side of the power switch so it is out of circuit while the set is turned off.
