1) Dog communication skills
2) Handler focus - yes, it matters no matter how old that puppy is! But I'm not talking boring stare-at-me focus. I'm talking about choosing to focus on the handler vs. focusing on the other dogs (this is huuuuuuuuuuge!!!!!!!! HUGE!!!!).
3) Building strong foundation for obedience via clicker
4) Explaining what clicker training is and encouraging its use <-- a lot of people are intimidated and/or don't understand what's so beautiful about clicker training. I would use my own demo dog to demonstrate what's so great about clicker training to encourage the folks to try the same. Specifically, I would do a lot a lot a lot a lot a lot a LOT of games. People get too caught up in what their dogs should so, how they should act, how perfect they should be, etc. I say, screw that. Take out a clicker, bring some treats, and play some games Puppies are supposed to be fun.
5) Learning "mat" or "place" or "crate". In other words, teaching the dog to go to a place and staying there <--essentially for learning calming behaviors.

Have you read Control Unleashed or seen Susan Garrett's Crate Games? They have wonderful wonderful wonderful games that you can play with young puppies to encourage self control and strong handler focus in the face of distractions.
