Imran if the course videos is the actual instructional information then yep you don't need to do much activation on the background books. Use the Direct Learning approach. Just PhotoRead them. Watch the videos and let the books activate that way.
If one or two of the books jump out as needing a closer look activate them some. It might be they give you more information than the videos to help you understand that part. So activation can be done after viewing the videos.
