I found this site by searching on Wikipedia, it's somewhat focused upon D&D game masters at times, but the principals are very helpful nonetheless. Tone, emotion, economy, geography, etc. It has a set of activities with it as well as hour-long audio files extrapolating on the subject of the week. I don't know if mods will go crazy about me posting a link, but I'm only trying to help... Shakespeare & Dragons
Some places see it as an advertisement and will suspend, ban, etc. But yeah, go to the site and click the topics for a set of notes and activities.
