Yes, invert the phase (180) on one sub only. If you get an increase in SPL, you're on the right track. :)

Most of the sound should be coming from the center channel (with movies and TV at least), so that is correct.

You've got a huge suck-out right around 50hz on each sub...I'd try moving them around and see if you can't take down the peak at ~27hz and fill in that 50hz null.

Actually, it's the opposite. If you get "full towers" you would need less of a sub (theoretically). With smaller speakers (i.e. bookshelves), the subwoofer becomes even more important.

From what I gather, this is not correct.

Audyssey can set distances longer than 30', you just can't adjust them. Not sure how you'd do the distance tweak, but that's what I've read here.

Ahhh, thanks tvuong. That makes sense.

That sweep above was done at -23dbsf and 0MV. When you say:

Yeah, if you have a mic with a sensitivity factor line in the cal file you will be unable to calibrate the SPL in REW. You're good to go. :)
