No question the learning curve for Moodle is steep. I remember it well.
The Glossary of Common Terms is helpful for learning, for instance, that what Moodle calls a "course" is what most people think of as a virtual classroom.
But, also, Mary has made a pile o' YouTube videos, as have others. They're short and have the virtue of being able to pause and repeat, etc.
Also, some of Mary's books, while aimed at teaching French, are quite good at showing how to do many teacherly things, like uploading a whole folder of files and making them available to students.
As with many new experiences, the real trick is to know how to ask a question in Moodle-ese, and that does take a while. My cheap search approach is to use Google and say something like "Moodle enrollment [something else]," which usually gets me to the documentation on [something else].
Enjoy!
