I think Doitsu covered most everything I know about configurations. As for controlling splits in the epub, I will add that there is another config option which more-or-less determines how to handle explicit page breaks in the ODF document. It is
Code:
<option name="page_break_split" value="explicit" />
I say "more or less" because in my experience it seems to interact with the "split level" option, and whether or not the heading level specified does or does not include a page-break option in the LO style definition. If you find you're getting blank pages in the epub, tweak these values. Likewise, if you are not getting splits where you think you should.
