Need help setting up Meridian861/800 system

I have a large complex system in a rather large room and need help in setting my system up both programming the meridians as well as accoustic treatment and speakers positioning.I live in the suburbs of washington DC .Any input would be greatly appreciated.
Get a laptop. The Meridian setups seem confusing but, with a little practice, they are fairly friendly. Just make sure that you save earlier versions as you try modifications.

As for placement and room treatment, the same laws of physics apply to this system as any other.

Where's your dealer in all this? Meridian dealers are usually quite supportive.
