I recently came across a nice brochure for barefoot running, publish by Vibram, for their FiveFingers shoes. This is specifically for FiveFingers, as the guide states, but in reality this is good information for any types of minimalist shoes. The foot exercises are fantastic for anyone, no matter the shoe type. The other tips they give are awesome for anyone using shoes without a traditional 'high heel'.
The main thing I want people to note, the proper ball strike while running. It's on page 9 of the attached brochure. This is a VERY hard thing to explain to people, it's not a toe strike, it's a ball strike. Vibram did a great job of explain the details of it.
