Thanks pbelarge.
A friend told me about the building so a workmate and I took a long lunch break and checked it out. While there, I left message for the building managers that I would like to shoot it and to contact me at their convenience. They did so in a few days and with permission granted went back for another look and to set up times with security.
During these two visits, I put together a list of shots to take in my head, but they were really just the main frontal shots and a couple of the pano's. Most of the shots were just me trying new things, playing with angles, and seeing what worked. I planned to be there between 1 and 2 hours and was there just under 3. The lighting was pretty poor for a lot of the shots, so I kept having to adjust my ISO so that my longest exposure was at or less than 30 seconds so I could autobracket. I also set a time to be there after most businesses were closed, but people kept walking through the shots anyway.
The other thing I had a lot of trouble with (if you couldn't tell) was white balance. They had every kind of light imaginable and it seemed like every shot had many different ones in them. I stuck the camera on AWB and let it do its thing, hoping it could sort out some of it. Not sure if that was a good move or not, but I guess it didn't hurt to much.
