Mix room requirements: monitors and Dolby Surround

[soundman2002]

I'd like some input on setting up a moderate-size Pro Tools mix room. The main use would be stereo & LCRS, for TV and independent documentary films. I need to figure out the best way to design one room for TV and film. Here's some specific questions and issues - any responses are greatly appreciated.

For TV, nearfiled monitoring is important. For films, the LCR monitors need to be further away (to simulate a theater environment). Could one set of monitors be positioned for both TV and film work?
OR, If I were to install the LCR "film" monitors above a video screen, and temporarily bring in nearfields for TV work, could I use the same surround monitors for both applications?

Here's my Dolby question. For LCRS mixing (not 5.1) do I need to have the room approved by Dolby? And what are the pluses/minuses of Dolby encoding and decoding hardware vs. Dolby plug-ins for ProTools?

Also, any room designers with this knowledge please email me your contact info.
