1. Qs8
2. yes they would be fine for rear channel, actual many prefer direct radiating speakers for rear for music.
3. The m60's would be fine, but for the small increase in cost you may want to consider m80's so you don't get upgradeitis a few months later.

ps: I assume when you say b-stock you are referring to the Factory Outlet speakers? B-Stock usually can include returns, Axiom does not sell returns, they are brand new speakers, so really not B-stock.
