I work in a NOC, 12hr rotating shifts, and we work 24/7/365 (and 366 on leap years :)). What I recommend is very comfortable fully adjustable high back chairs with a head rest.
As for monitors, you need to give them fully adjustable mounts, with nice high quality wide screen displays (Some may say standard aspect ratio, but seriously, widescreen would make my job SO much easier). 4 Monitors would be good too, 3 is good, 4 would be far better. Give them a powerful computer, and make sure they are kept up to date hardware wise, plus, if these people are technical, and you're giving them the keys to your castle, make sure they have admin rights on their own machines so they can fix minor issues without calling your IT Disservice Desk. Give them relatively unfiltered internet, night shifts get VERY boring. Make sure every telephone has a corded and cordless headset for comfortable use, holding a handset to the ear for long periods is hopeless, and wireless is good for short calls, but you need wired for anything long.
As for lighting, task lighting that the users can control is very important, as well as dimable overhead reflective lighting is important. As for desks, adjustable hight is important for comfortable use, and make them BIG. As for your video wall, make it a good size, and have it easily changeable if someone notices something important is missing, give them TV, hell, if you can, give them 2 'tvs', one for news, one for something else, and give them the ability to change the channels if they want to watch a hockey game at night, or if the olympics are on, etc, etc, etc.... Make sure the enviromental controls are good, and not constantly changing. Give them the ability to play music for the whole operation center, entertainment is BIG when working long shifts.
Give them a lounge to relax in before shift, or on lunch, or after shift. I think thats everything I can think of for now
