I run an atom smasher! I make antiprotons! I shoot a neutrino cannon at Minnesota! you bet my job is awesome!
These are just my experience. I've worked in SSN maneuvering (reactor plant control) rooms, and at Fermilab, the Experimental Areas, D0, CDF control rooms and now days, the Main Control Room.
Keep the racks sealed, front and back as much as possible, to keep dust in the room from getting into the electronics. You might (or not) be amazed at how much dust a control room can collect over a year.
Include a fair amount of sound deadening foam. again, it's remarkable how loud pcs can get, way moreso if you have to add fan cooled crates and such.
Stay away from trackballs unless you can get *really* *awesome* trackballs, they tend to collect crap inside and are usu. kinda a PITA to clean.
Beware of the temptation to put in q00l tracklights, as they have a tendency to cause a lot of glare. Keep bookshelvs away from the consoles as much as possible.
Have your operators face AWAY from the hallway. Consider keycard access to keep distractions down. Spend the money on comfy high-backed chairs. Kitchen immediately adjacent to the control room. Bathroom nearby. Consoles should go UP, not out; it's easier to look up than turn your head and it _will_ make a difference.
I would not curve your workstations; skooching from one point to the next in a curved layout requires a unique trajectory for each endpoint; straight layouts are easier to run your chair along.
Here's mine http://www-visualmedia.fnal.gov/VMS_Site/gallery/stillphotos/2006/0000/06-0022-30D.hr.jpg kinda big, and i'm in the picture! Looks old and clunky but we manage.

If there's a problem elsewhere, it's a cultural problem in that sector or institution.
