Should I change the Monitor Audio GR10's to PSB M2

I am in the process of putting together a home theater. The room is 10(d) x 14(w) x 8(h). It is an openeing in one corner and a window on one of the side walls. it is carpeted and the walls are moonstone. The equipment I chosen to put in the room is Monitor Audio GR 10's as the front channels, a Gold Reference Center and a Sunfire Signature subwoofer, Sunfire Ultimate Reciever and Sunfire's 7 channel power amp, Cardas Neutral Reference Speaker Cable, Monster's HTS 5100 Power and Line conditioner, Samsung 43" DLP TV. I intend to put the system along the closed sided 14ft wall. I have bought 4 echo busters, 2 bass busters and 4 corner busters. The couch is against the wall opposite the system. With the information given what advice can anyone offer? I am into movies and love instrumentals (saxophone / piano).
