I worked on my first XP project with John Boal.  He recently did a post on ScrumBut.  I have mentioned ScrumBut and Scrummerfall before, but this is a good, quick read with a few good tips.  A lot of the concepts carry over to XP as well.

 

I'll add something though: Make sure your stories have acceptance criteria defined before you start working on them. This way you know when you are done. :)

 

Enjoy.
