You can look at VTC Computer software training. They have hundreds of tutorials and several of Vegas. I learn Vegas Pro with an 8 hours video tutorial, a lot of patience and with the strong determination that I wanted to learn to edit videos professionally. About the workshops, why not created a "fictional workshop" like I did. I took my video camera and record me in three different angles, in the same place, and doing something different on every angle. Then I went to Vegas to make three clones of me. This was horrible, frustrating, time consuming (Weeks doing a 2.5 min video) but in the end I learn how to use Vegas. If you really want to learn make challenge for yourself and like Birdcat said "As a rule, read all you can"
The meaning of a movie are the characters, the life of the movie is the music, but the magic is in the editing.
