Tutorials for AS 3 are hard to come by, at least for applications since the technology is new and so radically different from AS 1&2. CS3 can handle AS 1&2, so honestly you can do no wrong by doing the tutorials for AS 2. In fact, AS 3 is not as widely supported by browsers - because people tend not to update their flash players often.
