I think "may" just means that for "Standalone media files such as images" 
other rules apply than for the files mentioned in the first 10 numbered list 
items. IOW you can license those files under the CC-BY-SA 3.0 or under one of 
the other licenses permitted by our licensing policy.

No. Yes. I don't know what "export mix-in media" means.

IMHO templates need to considered separately from media gallery files because 
documents are derived from the templates, but documents are not derived from 
media gallery files. Usually, the latter get included in a document, but 
usually this doesn't make the document a derivatives of those media gallery 
files. Of course, the author of the document needs to add proper attribution 
to each included media gallery file (if the license of the media gallery file 
requires attribution).

IMO templates that are part of the standard Calligra distribution should be 
licensed CC0. If the templates are super trivial (i.e. not a creative work) 
then they might not even be copyrightable, but it's better to explicitly state 
your intention. I think document templates are somewhat similar to code 
templates used by code generators. There are often special exceptions making 
sure that the generated code can be used under any license.

Templates that are not part of the standard Calligra distribution could be 
licensed CC-BY-SA. The license should be made clear to the user choosing such 
a template (e.g. by explicitly mentioning the licenses in the template 
chooser). The same applies to media gallery files and other stuff that's meant 
to be included unaltered in documents.

See above. I wouldn't add anything to our FAQ because we should avoid anything 
that could be mistaken as legal advice.

Ask this in the Legal and Policy Issues devroom at FOSDEM. But be prepared to 
leave the room with more questions than you had when you entered to room. ;-)
There is no easy answer. It always depends.

Yes. That's why I propose to use CC0 for basic templates.

You might also take a look at how LibreOffice or other office suite developers 
ensure that their users can use the templates provided with the office suite 
without restrictions. LibreOffice only seems to include templates for 
presentations (and templates used by its wizards, but they didn't work here). 
The template chooser doesn't show license information. :/ And the source of 
the one template (DNA.otp) I looked at also doesn't seem to have any license 
information. :/

IMHO any software that allows "in-app" downloading (or even just choosing) of 
user-created content should do this, e.g. GHNS (or whatever it's called 
nowadays). For a not ideal example see Firefox's Get Add-ons (where the 
license resp. the EULA is hidden behind a link).
