Welcome aboard, looking forward to seeing the final product.
Good choice of subs there, I think any sub from one of those manufacturers would be an excellent choice.
If the front are to be wall mounted I would suggest looking at the M22 in/on walls for LR and then a VP100 or 150 in/on wall for the center and then the QS8 for surrounds, they all have a good timbre match and sound very close to their bookshelf design brethren; when combined with one of those subs you should be good to go.
I might also suggest another vertical in/on wall speaker for a center as the horizontal dispersion is superior to that of the VP series but your room doesn't look to be overly wide and I will guess all seats will be directly in front of the screen.
