Amongst others, yes.  The reports use the scheme bindings, but there are
more APIs wrapped than just those used by the reports.  For a while back
in the 1.x days the gnucash "application" was actually a guile script.

It depends.  There may be some docs in the wiki, but the primary docs
are probably in the "pythondoc" sources, which means they are in SVN.
For now the best way would be to work with the active devs and supply
documentation patches against svn trunk (or git's trunk, if that's how
you roll).
