Hi,
Are you brailling all of this material as part of a trial manuscript? Chapter 19 of the Instruction Manual tells you how to do all these preliminary pages but not all of these types of things are included in the trial; manuscript. If they are to be included, I would follow print. If there is a title, it should be centered. Can you attach a scan of the pages in question? Without seeing them, I am of the opinion that they are not necessary for the trial manuscript.
In regards to an emphasized title, the italics is not necessary unless for distinction (which doesn't seem logical here) 🙂
