Ben Ari and Ran Dolev are both remarkable UAG champs at Microsoft.
During the last months, they spent a lot of time to consolidate their deep knowledge and wrote a book about UAG. I am sure, the book will become your UAG-bible. See https://www.packtpub.com/microsoft-forefront-uag-2010-administrators-handbook/book for more information and how to purchase the book once it is out.
