Loaded questions there intowin, you should post it on axiom's forum as there are many more people there that could answer it.
Now in my opinion the m22 plus the EP600 is nearly as good as the M80 +ep600. As your room is medium to large I think the ability of the floor stander to really project the sound better would be better suited if you are into more of a party scene and looking to fill the room. If you are more interested in a close up listening experience then the M22+EP600 is the way to go. I feel this combo only leaves a little of the upper bass out of the equation, which sounds to be more analytical and detailed than the M80s, not that the M80s lack detail, just they have a slightly warmer sound.
For the surround question if you want a more immersive feel to your movies then the QS8 is the way to go and it does a very good job with multichannel music too. If music is your sole purpose then you could go with any of the in-wall or on wall speakers as they have very similar sonic qualities as their bookshelf cousins.
As I have not mentioned the EP350, you may think it is not to be considered, that would be wrong, it is a very nice sub for the money, but it doesn't have the frequency extension of the EP600 or even the EP500. I would stick with the EP600 if you can afford it, or drop to the EP500, the extra extension these 2 subs offer over the EP350 is worth the money. If you really want to stay to a lower end budget then by all means buy the EP350, it does an outstanding job as well.

. I personally am no a fan of the M3, too laid back for my tastes, the few Energy RC series speakers I have heard sounded more to my liking than the M3's but I like a forward sounding speaker. The VP150 is more forward sounding than the M3s so I like it paired with either my M22s or my M80s. Best way for you to know for sure would be to order up a set and have a listen, you have 30 days to return them and if you so desire during that 30 days you can send the M3s back and get M22s for just the price difference of the speakers no shiping charges for this change up, if you still don't like the Axiom's then you ship them back at Axiom's cost of shipping, M22's I believe are $30. Small price to pay to hear speakers in your own home(which is the second most important part of the whole audio scenario) for 30 days.
