Org keywords are any keyword you can think of, excepted INCLUDE
keywords. Thus, it makes sense to have an OPTIONS keyword within
a SETUPFILE.

For each keyword related to export (e.g. AUTHOR), there's
an :EXPORT_AUTHOR: property for subtree export. It is also true for
back-end specific keywords (like Beamer's).

Not at all. Each include will be replaced by the contents of the file it
points to. You can have as many INCLUDE keywords as you want in a file.

Though, if first INCLUDE keyword adds an Org keyword (e.g. AUTHOR) and
the second one also inserts AUTHOR keyword, the last AUTHOR keyword in
the buffer will have precedence over the first one.

The same holds for SETUPFILE keywords.

That would probably work. But, again, I highly suggest to use SETUPFILE
for setting up the export (among other things). Use INCLUDE when you
need to add contents, not only Org meta-data.
