I have a question that I'd like to post. Any assistance appreciated.

On each 2013 Database there is the scheduled maintenance and the 24x7. Does the scheduled maintenance run along with the 24x7 or is it a option of one or the other?

Scheduled Maintenance is deprecated in 2013. Its all workload based.

The background maint is really database checksumming.

This is for 2010, but applies for the most part:

Bottom Line: I would leave the defaults as is. That makes Exchange happy.
