I just got a firm foam anti static floor mat for my workstation, and it is the greatest money I have ever spent. Even standing for 20 minutes is greatly improved by something a little squishy under my feet.
If any person might be standing in some spot, put one on the floor.
As for software and digital copies of stuff, buy a big honkin NAS device and store everything in ONE PLACE. Just the fact that its on the same physical machine eliminates people's need to search anywhere else.
