I just looked back in the posts and seen all the things you are wanting to control.
Although the MX-990 can easily work all of that, for someone that appears to not have much knowledge of control systems, this is going to be a long & difficult journey.

Is there a drop down screen that goes in front of the Sony TV? Or are we talking about 2 different rooms?

How are you setting up the Home page to work for the 2 different viewing situations?
