Lorenzo, welcome. Within reason, speakers can never be "too much" for a room, since you play them at the loudness you want; they don't control you. The 60/500 would certainly be excellent and a very substantial improvement over your present setup, but an M22 based setup with a smaller sub would also be good if it fits your budget better.
As to the receiver, again if it fits your budget, the 2700 would be excellent. If you would be interested in something less expensive, the Onkyo 604(available for around $380 from sources such as B&H and 6thAve)is a significant bargain.
