Supernatural Encounters Prep: Droids Cartoon
Of course if Joe's going to have you go through the Ewoks cartoons he's surely going to address the Droids series as well. Though I didn't see the comic series on his list of suggested reading, I'm sure it wouldn't hurt to add that either to your list if you're so inclined.
With the voice of Anthony Daniels the series isn't as bad as you think and it adds a lot of credibility to the show to have the voice of C-3PO be a part of it. It's whimsical nature is light-hearted fun for kids but with a lot of creativity from George Lucas since he allowed the creators of the show to search his vault of unused ideas for the movies. This is why you see a LOT of ideas that would be used in the prequels years later.
Worth the watch!
