In case you can't help yourself and want to tweak:
Master Set Procedure for speaker set-up.
I haven't tried it yet, but am going to before I start buying/making room treatments.
Supposedly, it works better for a long wall set up like yours. And if done properly, a room shouldn't need treatment. It's free.

cheap place to buy absorption panels and DIY supplies, Corning 703/705, proper cloth:

Diffusion Panels (kinda look like egg carton cardboard material you can paint):

I have an extra box of this stuff, so let me know if you're interested.
Hope this helps.
