Your LFE should stay on 120hz because that .1 channel in 5.1 is meant to go to the sub.
With the individual speaker/sub crossovers, use whatever sounds best to you as long as you don't go lower than what Audyssey recommends. When Audyssey picks your crossover, it sets it to where the speakers start to roll off. So that's the bare minimum. But many people go higher, and it really depends on your room, your speakers, and your listening preferences as to which is best.
As for the subwoofer channel level, optimally it should end up near 0db after Audyssey takes its readings plus whatever bump you might add to the subwoofer channel for extra bass (if any). If the subwoofer channel is a lot lower, it can help to turn the gain (volume) down slightly on the sub and run again. The reason is that if you have the subwoofer channel at say -10db, that means Audyssey has to attenuate the signal downward because the sub gain is a little high. Why not match the sub gain sensitivity to the receiver better so that Audyssey doesn't have to change the signal that much? Some people feel that they bass response of your sub improves slightly when it is better matched like that. Maybe it's my imagination, but my first time configuring Audyssey with that method, I thought the bass tightened up a little from my sub.
So if you know you want to run the subwoofer a little hot (say extra couple of db in bass volume), then you would rerun Audyssey adjusting the gain until you got to about -2db for the sub channel, then turn it up 2db. Otherwise, shoot for zero db.
