1) I'd like to know if the diffusion I have is useful in a control room such as I have, or if I should concentrate on absorption instead.
2) Is it more useful for me to place absorption behind the speakers or on the back wall, assuming diffusion is not to be used in this space.
In detail:
Room = 14.25'(l) x 8.5'(w) x 9'(h)

Doors and window not to scale, walls are to scale.
I own:
(3) 4?x2?x1? rigid fiberglass panels
(2) 4?x4?x1? rigid fiberglass panels
(4) 4?x2?x5.5? GIK 244 bass traps
(4) 2?x2?x5.5" Auralex T?Fusor plastic diffusers

The stuff I have is kind of "hodge-podge" since most of it came in a big used lot from a craigslist posting along with more stuff I'm using in another room.
I have the 4?x2? panels hung 3" off the wall on either side of the listening position at the first reflection point, and a 4?x4? panel hung above as a ?cloud? at that reflection point (~3" off the ceiling). I have the other 4?x4? panel hung as a ?cloud? over the north side of the room. I have 2 bass traps straddling the corners behind the speakers hanging vertically and flush to the ceiling, and the other 2 bass traps straddling the other ceiling corners hanging horizontally (since the door is in the way for vertical hanging).
I?m wondering what to do with the diffusion and the remaining 4?x2? panel. My first thought is to use the diffusion on the North wall, behind the listening position, and place the remaining 4?x2? panel opposite the windows. Or would the 4?x2? panel be better placed on the South wall between the speakers, or instead of the diffusion on the North wall?
I know I should try stuff, listen, measure, etc., but I'm looking for a head start from the experts!
Thanks!
