UPDATESpeaker & Treatment Placement (Smallish Room)

[technocolour]

Hi, I'm looking to finalise my room. I intend to trap the main 3 vertical corners (all but the one with the door) with 200cm worth of 50cmx60cmx80cm rockwool superchunks. I also have about 250m of slightly smaller traps (about 40cmx50cmx60cm) I was intending to put on the wall->floor corners. I have 5 wall-mounted rockwool absorbers (60cmx100cmx10cm) that I was going to place at the wall early reflection points (1 at each spot) and the back wall (3 absorbers). I also have 7 thinner rockwool absorbers (100cmx60cmx5cm) that I was going to place around the room. Finally, I will have a ceiling cloud (180cmx60cmx10cm) I intend to place at the ceiling early reflection position. I guess my questions are:

1) Where would you setup the speakers & listening position?
3) With this in mind, where would be the optimal place to place the cloud?
3) Is the treatment I have set aside adequate for the dimensions of the room?
4) With the 7 thinner panels, where about in the room would would these be best utilised?
5) The room has a bay window (curtains + wooden blinds). Whould some panels be placed here?

I understand that no definitive answers can be given and I intend to measure + experiment along the way but I would be most grateful for any info that can put me in the ballpark.

Thanks!
