Yikes, that is one tough floorplan to set up for HT. looks like you may need to use stands for the QS8's or ceiling mount them. Is the TV going to be in the console or just the av gear?

My first suggestion would be to have the TV and LCR on the left hand (4100mm) wall in the Living/dining room that is the most central in the floor plan and then you could have the surrounds mounted on the backwall to the sides of the listening position or flip it 180 deg.
