Just chiming in for my 2 cents.
When you think you have everything setup you can just grab any Star Wars dvd (everyone has at least one, right?) and go to the THX menu setup and run through the speaker tests. It will pitch sound to each speaker and show you at the same time on the screen which speaker should be getting sound.
At least this way you'll know you have all the speakers setup correctly, as long as you are using a digital coax or optical wire from your dvd player to your receiver.
And I guarantee you when you get everything setup yourself, you will not let anyone else touch it.
