N-set, if you have an unused circuit in the apt., then its neutral may be an acceptable ground path (neutral stays "on" even when breaker is "off"...).
Re, the phono calibration, I have expounded the SRA at length in the "Vinyl Ceremonies" thread. As for tuning the gain stage(s), I'm afraid this can only be done by ear when all else is well. As for the cartridge "loading", I started out with a "made-for-each-other" cartridge/SUT pairing and went from there to a standard 47k Ohm "mm" level of gain, since I prefer the SUT to extra active gain.
Anyway, I hope your RIAA is dialed in, so you are not asking about this!
