New Room, need advice

I'll be moving into a room next month that I've only seen once. I need advice on where to place what. I will have to work with what I've already got and maybe a few hundred dollars to start. Right now I have 6 panels of Roxul Rockboard 60 on order and still have to build the panels. I have 7 pink fluffy traps in these sizes (dimensions in feet): 2 3x8 2 3x4 2 4x5 1 5x6 What is drawn is all I know about the room. There are windows on the top and left walls, 2 on each, but I don't know where exactly. The door is on the bottom wall closer to the left. There is also some large ductwork across the entire right wall. The floor is concrete with carpet, the walls are wood studding and plaster. I will post more info when I get it, but I'd like some ideas of where to place my monitors, rack, mixer, and computer with dual monitors. As well as where to place vocals for recording. I cannot build walls in this space, for now its what i've got to work with, but there is a live room connected, so it will be mainly a control room. Maybe guitars/vocals as well. I'd like to get some ideas so I know how much more treatment is needed and where to optimally place things.

Typically you would want to have your monitors firing down the length of the room. In a room as big as this, it may not be as much of an issue....still, it helps to balance the listening position. Look for "reflection free zone" using the search function or Google it...you will still get John's site...I think that is always cool :) The treatment issues you are going to deal with is the 10 feet tall ceiling and the 20 feet wide room. So treatments according to a reflection free zone are going to help, but you will most likely be in need of a hard backed overhead cloud at the listener position to break up the room modes that the divisibles produce and support.
