We sent nine people to CSM training last week. I can't recommend it enough. They see the light. The one practice I'd suggest is to get them together in a room and talk about what they learned and reflect on how the company is using Scrum. There's not "one way" to do Scrum. You are encouraged to change the practice as you use it to fit your environment. It is useful to "follow the rules" at the beginning to learn the reasons for Agile let team ownership soak into the culture.
However new CSM grads can be a bit fanatical. Talk it through before they hit the team!
