Ghost, welcome. I'll try your questions: 1) Yes, the M22s would be ideal for your room; 2)for your uses a more powerful sub would be helpful, and I'd suggest using about $350 for the Hsu STF-2; 3)get the Onkyo 508 which Tom has linked in his reply; 4)depending on how much distance from your listening position you could give them in that setup(hopefully at least 6-7' so they have some room to disperse the surround sound), the M22s would do reasonably well as side surrounds, but the QSs inherently have the wide dispersion which is so important for surrounds.
