I added one point light in one of the florescent fixtures with a Blur Radius of 8 and Shadow Samples to 8, and set the three Hallway lights to a Blur Radius of .5 and Shadow Samples to 8.  This took just over 50 minutes to render, and now that I can compare a couple of renders, I think I'm going to need to set the Shadow Samples up to 16 for my final renders.  I can probably deal with the noisiness of the shadows with a lower sample size for draft work, but really need to increase the samples for final renders.

If there is something I can do with the render settings that will speed this up, I'd love to hear about it.

As always, thanks for the input.
