A lot of questions ;-)
I have the situation that I have a website in English, and that I need to translate only certain pages into another language. In this case, I don't want a full translation of all the pages. The easiest way to achieve that is by allowing certain mods to moderate only their own pages. One solution would be to have a class 'can be edited by' per page like the listbook/chapters. I've been experimenting with lb/ch but perhaps I'm missing something, I can't get it to work.
