Excellent advice from Tboooe, IMO. Also, I see in your system description thread that you'll be moving to a different house in a few months. Hopefully that will provide a much better acoustic environment for the speakers than you have now. I would suggest slowing down and not investing a great deal of money in trying to optimize the system until that time. Otherwise what you may end up doing in the meantime is making changes that band-aid room acoustic problems, but won't prove to be optimal when the speakers are in a better environment.
