Welcome to the forum xanstin.
The M2's would be great. If you have the ability to place a vertical M2 on top of your t.v for your centre channel (instead of the VP100) that would work awesome and can save you money in the process towards the EP350 subwoofer. I think it would be well worth the extra money for the EP350 because video games (ps3, xbox360) and blu-ray movies have such spectacular LFE moments, not to mention great surround use in which the QS4's will just envelop you in. I think you would be floored with this type of setup in your small room.
Also you can order from the factory outlet which offers 10% off.
Cheers!
