Use a tool like PHPMyAdmin to export the data. It is stored in the mdl_user table.

The global settings are only used as defaults when a new quiz is created. There is no interface for changing all exisiting quizzes.

If you are brave, take a full backup first, and know how to use a tool like PHPMyAdmin, then you can directly change things in the database. Something like

UPDATE mdl_quiz SET shufflequestions = 1;

That should correspond to the MOODLE_161 tag in CVS. http://moodle.cvs.sourceforge.net/moodle/moodle/version.php?view=log#MOODLE_161

The diagram here may help: http://docs.moodle.org/en/CVS_for_Administrators

The MOODLE_16_STABLE branch has gone past the 1.6.1 release through 1.6.2, etc. and is currenly at 1.6.5+, meaning after the 1.6.5 release.

If there were simple instructions about how to make this work, then it probably would already work in the official release.

There used to be a new module template, but it has not been updated since Moodle 1.6, and lots has changed since then, so it is not very useful. MDL-4671 is the issue about updating it. Don't hold your breath - everyone is very busy.
