You are very welcome.
OK - yes, leave DEQ on and DV off. Good idea to factory reset and rerun Audyssey.
Set the LPF of LFE to 120Hz. There can be content in the LFE channel (the .1 channel) up to 120Hz so it's best set to that.
It's fine to run the AVR near 0. After you have done your testing with the new Audyssey calibration, if you want to have the MV running a little lower, Jerry's suggestion above is a good one - raise all the trims by the same amount (a few dB will do) - that preserves the result of the calibration.
Don't hesitate to come back with more questions if you need to.
