Thanks so much for your questions.
It's been a bit confusing lately as to which reference should be used for which type of situation.
The 6th edition of the Literary manual does cover some areas that are not addressed anywhere else, but your questions specifically refer to formatting.
Formatting should be referenced in the 2011 Guidelines. It sounds like the agency you are brailling this project for, may have some of their own criteria or agency decisions.
Sometimes different agencies will have a specific format that they prefer to use for title pages, formatting, etc. I would strongly suggest that you direct these questions to the contracting agency.
I could answer your questions according to the guidelines, but your contracting agency may want something completely different.
