In otherwords (all done in the settings window):
[1] I set levels with the RS Meter using the AV master volume to read 75db at the RS meter
[2] Adjust my settings (Output, Wave and Input to around 12-14 db on output/ input VU meters)
[3] Run REW calibrate SPL with the settings of the RS meter - again @ 75db

Excuse my numbering of your quote, but I want to direct you to number [2].
Changing the Output level will alter the 75dB reading on th RS meter.
You should
[1] Set sweep to -12db
[2] Set Wave to 1.000 and Output to 0.500
[3] Adjust receiver volume to 75dB on RS meter.
[4] Set Input level to proper level ~-12dBRMS.
[5] Run CALIBRATE SPL routine and set REW level to 75dB
[6] You could run Set Target Level routine at this point and it should verify around 75dB....
[7] Measure
