I used to work for a large insurance company in Chicago. The director charged with building our NOC in 2000 basically traveled throughout the country visiting other large IT organization's NOC's and took the best ideas and made them work for us - and it did resemble 24.
Take a large crescent shaped room with a 30' or more ceiling. The video wall was three different sections (this is important for separation of displays and multiple tools at the same time). The display units were high end rear projection systems that were each hooked up to computers that drove the display and were roughly 3'x5' each. Of course there's no seam or separation between the screens. Any group of screens can be used to display anything you want (1 screen, 2, 4, 6, all, etc). Pretty basic stuff nowadays, but it was great ten years ago. The left and right banks had three screens stacked on top of eachother, by either 4 or 5 wide. The center bank was 3 high by either 8 or 10 wide.
Three rows of crescent tables with low walls in front separating them, and minimal separation between workspaces - you want people in a NOC to work very closely with eachother, especially in case of an outage. Each station had two or three LCD screens mounted on articulating arms, but not to be stacked on top of eachother like those trading desks you see with 6 or 8 LCD screens at them. That would be too tall, and you couldn't look over the top to see the main video wall without standing. The room sat close to 50 people. Around the edges of the room are various cabinets, printers, personal storage for the three shifts of employees that work in the NOC, etc. Of course high end chairs are important as others have noted. Lighting is also equally important. You have to be very careful with making sure it is as close to natural lighting as possible. The lighting we used was recessed and inset so that no lightbulb shone directly out or down on the people - it made it less harsh, but still very bright in the room based on a good design. Wireless headsets are important, and also minimizing speakerphones and any other distracting noise.
Behind the rows of tables at the back of the crescent in the donut hole section if you will is an enclosed room large enough to sit 30 people comfortably with power, phones, and network connections to cover it. The walls facing the NOC are floor to ceiling glass, and it has connectivity to the videowall of the NOC so that displays from their can be sent to the meeting room as well. It has every high end normal conference room tool you could need - multiple video conferences, smartboard, integrated microphones and speakers, etc. Everything was hidden inside builtin cabinets made of high end wood. This main room is the situation room. During a large outage, 2nd and 3rd level staff will work out of the room in conjunction with the NOC teams. Directly upstairs from the situation room is another identical room, also with floor to ceiling glass walls looking out to the video wall of the NOC. This upper room was reserved for senior and executive management use during a large outage. Engineers and Executive management have different needs during an outage and require separate spaces and separate functions, although constant information does need to feed between the two. The upper room was more of the showpiece room. It had a motorized curtain that you could press a button on the wireless control panel to open and close. The entrance from the building going up to the second floor board room does not give anything away for what the NOC itself looked like, so once everybody was assembled in the room and the button was hit, it never failed to impress first time visitors. They would always leave their chairs at the conf table and walk right up to the glass wall to look down at the people working in the NOC and see what was displayed on the board.
It was an extremely impressive setup. I am now in sales and visit customer sites on a daily basis and I have yet to see something that even approaches what this director designed at my old employer.
You can't forget to include cable or satellite to display weather and headline news. For fun, don't forget to include a high end stereo system and a blu-ray player so you can watch movies or the occasionaly superbowl game since you already have cable service anyway.
