Thanks for the information. I talked to a good mechanic at a local shop today and he said everything looks to be in good shape on my BB. I'm going to reuse as much of it as I can, at least the cups and bearings, which are in good shape.

I might possibly have to change the spindle, since I am converting this to a single speed and might need a different length. Also, I'm going to try to use an old Shimano road double crankset as a single and not sure of spindle/CS compatibility. I'm going to try it all out and replace as needed.
