I just read somewhere that it's perfectly acceptable to just place the diode across the Selenium rectifier, leaving it in the circuit, this is because Seleniums never short, they just go up in resistance until they fail.
As for adding resistance you'll need to get it running and check the B+ against the spec and adjust accordingly.

Although some might consider it to be a "sloppy practice", I usually just bridge the seleniums with the diode... the original appearance is preserved and I have never had a problem.
