Thanks for the interesting questions.
1. See Sample 2-9 in Formats for placement of the transcriber's name on line after "transcribed by"
2. The termination sign is not itself a font attribute, so it is never grouped with font attributes. As you noted, it has many uses, only one of which is with font attributes, so it is always grouped with the miscellaneous signs or by itself if all the other signs in use can be categorized. I don't think it fits into a category.
