This book is already published: http://www.packtpub.com/ext-js-4-first-look/book
M (http://www.packtpub.com/ext-js-4-first-look/book)aster Garcia is working on his second edition: http://www.manning.com/garcia3/
T (http://www.manning.com/garcia3/)his book is not finished yet but if you buy it you can start reading 100 pages.

Furthermore, there are many tuts... You can also buy a great JavaScript book and look inside the Ext JS code. My great JS book is: http://www.amazon.com/JavaScript-Definitive-Guide-Activate-Guides/dp/0596805527
