I like your approach adding all the clips. Is this a completely online course or a 'hybrid' in classroom with an online component? I've taught at the college level for 12+ years (computer science and networking not music) and I've found I almost always need to simplify things more than I originally thought, even for college level students. My suggestion would be you add a little more explanation of what you are doing when playing during the clips. " In this clip you are going to hear me play X,Y,Z over this chord and you should listen for ......etc."
Enjoy teaching it and don't be too hard on yourself - the first time around teaching any course it is always a little rough around the edges until you learn what works for students and what doesn't.
