Sounds like a good idea.
If you are investing in LED lighting, which is superior to CFLs, please be sure to also match your screens with LED backlighting. You want the highest CRI on your light sources. Sunlight color temperature is 5500K, incadescent is 3300K. The post about 4200K is spot-on.
Dimmable light sources are a must.
Oh, and consider screens that are color-correct. I have 2 monitors on my desk right now and only one of them is easy to calibrate for colors properly. 42" industrial panels for the video wall will probably be more cost-effective and easy to replace without mounting headaches as the standards are well-established now.
I am designing a NOC as well, so I am looking into this as well.
