If the floor space allows, go for the floorstanders, the full range they produce is much better than any of the other possibilities. My HT area is 12x16 and open to another 12x16 in an 'L' shape, I have M80s, VP150 and 3QS8s, so I say go for the full out system and never look back. Everything sounds amazing and I just set the receiver to pure direct for 2 channel listening through the M80s. Then you have the best of everything for SACD or DVD-A and movies.
If you are unable to accomodate the floorstanders then either of the 'W' series possibilities you have chosen will work great as well, although I favor the W22 scenario a little more; it's more personal preference for the better(more pronounced) mid range the 22 series has over the 3 series.
