I highly recommend the book by William Rice (currently being featured on the main page of moodle.org).  It shows you Moodle from both the teacher's and administrator's standpoint.  So whether you're going to use Moodle as a teacher or install your own site, it's a great place to start.

Hi Markus,

take a look at

moodle.de
moodleschule.de

There are several printed documentations in german.
