Hang corner traps along the ceiling corners and you'll get a vast improvement.

"Planning on using 5.5 Ultratouch" is kind of meaningless, it all depends how you're using it. You want big traps with big space behind them, is all, and corners are better, for all the reasons listed earlier.

If you can take your 90-degree ceiling corners and turn them into 2-foot angled traps all the way round (or even just in the 3-way corners), you will create a vastly better acoustical space.

Any corner is as good as any other when it comes to bass-trapping. From your drawing, I count two 3-way corners that are currently just walls and ceiling, unused space. Also the wall-ceiling corners over the sofa and mixing desk. Covering those with corner traps will make a massive difference. If you want to go further, the closets could be bass-trapped top and bottom, or the doors could get a heavy insulator on one sideor another or both and be left partway open. Insulation could be stuffed under the sofa or tables, perhaps.

You could also build one or two absorbent gobos of whatever size is practical (bigger the better, but anything helps), and create a movable "dead corner" to sing or play into, or even just a big absorber in the room to kill some of the worst resonances.

When it comes to bass trapping, any is good, and more is better. The less room you have to fit in even a little bit, the more good that little bit will do. The point is not to "tune" the room, just to kill as much bass resonance as you possibly can, so that you are hearing bass frequencies from the speakers, not from their effects of bouncing all over the room and screwing up your frequency perception.

The general tendency to stick egg-crate foam all over the walls is actually on the right track, although totally the wrong approach. As long as the absorption is physically DENSE and DEEP (or DENSE and well-separated from the walls), it is a good thing, and you can just put it anywhere. The problem with the egg-crate-foam approach is that it often soaks up all the LEAST offensive reflections, while leaving the MOST offensive ones. This makes it sound like a bad recording in a bad room instead of a good recording in a bad room.
