EP, welcome. The M2s would work well in your room if you don't need extremely high sound levels. Likewise, the 50 watts of your 108 would be fine unless the levels got really high. For $1,000 I'd suggest 2 M2s up front and since you're thinking mostly HT, use the wide dispersion QS4s for surrounds. A sub would be essential and for around the remaining $300 in your budget consider the Hsu STF-1 or the similar Outlaw LFM-2. You can temporarily do without a center speaker and use the M2s to create a "phantom" center. When your budget permits you could consider a vertical M2 or a VP100 for a center.
