No trouble with FO speakers, here. I would definitely order that way again.
I absolutely disagree that a VP150 is warranted in that size space. VP100 is a very good speaker and certainly adequate.
The QS speakers are awesome and seductive. I love my QS8's. HOWEVER, they are expensive when you're on a budget. Going to (onwall?) M2's for the surround speakers saves you ~$200 which could be applied to upgrading from the M2 to M22 for the mains (which I definitely recommend). A lot depends upon how much flexibility you have regarding mounting the surrounds.
I agree with Ken that M3/QS4 would be just great for that size space, too. If it was me, I'd try to figure out a way to get the M22/QS8, though.
You definitely don't need 7.1.
I don't know what they're getting for shipping, but Outlaw has their LFM-1 Plus
for $467 right now, which seems like a very good value. Hsu helped design it, I believe.
Good luck! Enjoy the journey!
