Not to be too mundane, but I have replaced most of the lightbulbs in my house, as well as my studio, with daylight compact florescents and my screen callibrated accordingly. Though I hear complaints about these, I bought them in bulk and any that flicker--typically one or two a dozen--I don't use or put in outside sockets.
As I still have many slides and negatives, I have a current Nikon film scanner. Also various solutions and pads to clean the film before scanning. Of course I have a modest sized light table for viewing. I used to have a huge light table that I could lay out a two-tray slide show on, but as now I only work with a few slides or negatives at a time....
I recently built a new photo studio building 14'x24' at my second home and had the luxury of putting up huge strong deep long shelves, two lower shelves being 6 inches high for laying out prints flat and for boxes of paper from letter to 17x22 and then larger shelves below for roll paper and up top for upright supplies. This is situated over one end of the desk and over the built-in table for my two printers, ipf5000 and r1800 so that I can just spin from the screen to the printer and just stand up right there for any supplies I need or to place prints. Though I have not had a problem with stacking prints bleeding into one another, for my better prints I interleave acid free paper if it is not going right into a mat.
Other things:
Paper cutting board, sharp knives, straight edge and t square, mechanical pencils.
A lovely comfortable architect/executive chair with lots of adjustments, casters, and ability to tilt back so I can put my feet up if I want.
Two large cork boards, from Staples, that I have rigged up with callibrated lights, for comparing images and posting temporary favorites.
Finally(not really!), I have a mat cutter and always a dozen or so sheets of mat board and foamcore.
