I can understand the frustration. I had to work with table of authorities and contents before too.

Your sources got into a mess. I presume the TOC is fine?

What do you mean by got in a mess? As I understand, styles are pasted into a new document if they are part of the selection that you are copying. In any case, for citations and such, there is a field code surrounding the text you are citing. If i am right, as long as the field code is copied into the other document, the source will be included into the biblio when it is updated.
