Pat, all sounds normal and as others have said he should "walk out of this tunnel" in 2 to 3 weeks and begin his recovery. Re the mucous, be prepared for when this phase ends the dry mouth phase usually begins. For most it's really severe at first. Not painful just really really DRY. I had to keep a water bottle in every room of my house and every car was equipped with several bottles as I would always seem to leave my bottle somewhere in a store and not remember until I was driving off. The dry mouth phase along with his taste will recover slowly over the next 2 years until it reaches his new normal. Tell him that he needs to be patient as we have not found anything that speeds up our post Tx healing process.
