Check out this thread which has good advice. Mainly, the more decorations, award banners, etc., you have in the pit, the less work space you have and the fewer people you can have in the pit at once. Also, some events give you a spacious 10x10 pit area. Others are tighter and give you 9x9 or even a little less. Try to keep the pit open - it can get really hot at some events in the pit area. And you might need room for a tall bot (not this year, but in past years).
Many teams use their robot cart as the work bench for the robot.

MOE has two rolling carts which make up the majority of the pit - designs can be seen here. I don't have a picture, but there is also a white board listing match times and results, a scrolling electronic sign (small) on top of the carts giving safety and inspirational messages, and a small wire shelf case with buttons, team materials, info for judges, etc.
