My take:
Floorstanding fronts.
QSx for the surrounds.

As for the centre, is width the problem or height? I believe the VP100 is just as tall as the VP150, but it is not as wide. Check the webpage specs and do some measurements above your tv. Various mounting brackets for back walls are also possible.

Subwoofers vary depending on your budget. In keeping with 2k to 3k i would say Hsu or SVS, otherwise go with an Axiom EP500 or EP350.
