Moodle in English

There is a plugin that might help with this: https://moodle.org/plugins/profilefield_file

I suggest you back up the Glossary as a course backup file and restore it on your other installation.

Images have to be embedded into the Word file using web-compatible file formats such as GIF, JPEG or PNG. There is some more documentation on handling figures on a new Moodle document page I just added at How to prepare a Word file for import into a Book. 

I don't know of any plugin that allows book chapters and sections to be re-organised. It would probably need to work a bit like the Categories page on the course Question bank, I imagine.
