Minor logging fix and minor import corrections

[todd-cook]

changed code to return default logging level if logging config is missing Added missing import statements in three files that could cause errors which might be hard to track.

These are great, and I definitely appreciate these. I notice you are still making updates though... did you want to mark this as draft until you are ready for me to merge it?
