This bit of news is a little late, but hopefully still useful to someone out there who's interested in introducing agile practices to their project.
A few months ago, Addison-Wesley released a great resource for teams and coaches relatively new to agile methods: Agile Adoption Patterns by Amr Elssamadisy. Unlike much of the Agile literature, this book doesn't just tell you what the end of the long road to agility looks like. It tells you how to get there, from where you are now. This book won't solve any problems for you, but it'll help you recognize the problems you'll face, and it'll arm you with some tools to deal with them with a minimum of pain and frustration.
I've reviewed the book for InfoQ, so you can read more of my thoughts on it here.
