Hi Francis,
in addition to Mary's and Matt's relevant tips, I found most helpful the book: Teaching Online. A Practical Guide regarding structure, tips, etc. I also think that the course that Mary recommends is a best-practice example of a well-designed online course.
Then, regarding quality and proved techniques for teaching and learning online and with multimedia, I'd consult any article or book from Ruth C. Clark and Richar Mayer. The books are lengthy and deep but they have some articles that summarize their principles in a very understandable way.
