here's what I would do:

center: VP150
front mains: whatever you want, at least M22,
rear speakers: depends.. either QS something, or even regular bookshelf or tower speakers. M40's are on sale.

the 6 and 7th speakers, i'd get QS8's and mount them on the SIDES of the room, not to the back, or to the front. This, I believe, would create the best sound dispersion. I hate having 4 speakers behind me and 3 in front.. 3 in front, 2 on the side, and 2 in back is the best, as long as your room has the proper size for this to work! a rectangle works best in this setup, assuming you sit relatively in the middle.
