It looks like your room would work fine for home theater.
For 2 channel as has been stated the Focal's should be brought out into the room about a 1/3 of the way, sit about a 1/3 of the way back and with the other 1/3 behind you. Then experiment with the distance from the side walls, min of 3 feet from side wall. You want to move them inside until the center image is where you like it.
These are just starting points but adjust from there.
