Insulation
I am using R38 batts to insulate above the ceiling of a new room that I am building. What do I do about my ceiling boxes, 2 which will be used for light fixtures and the other will be for a ceiling fan? Must I leave a space around and atop the boxes?
Thank you.

No. Bury them. 
You can even take it a step further and cover all the holes in the electrical boxes with foam. Just don't squirt it into the box. The only exception is recessed cans that are not IC rated. Those you have to keep insulation 3" away. Cans that are IC rated can be covered with insulation.
