The second edition of the book written by Shea Frederick, Steve "Cutter" Blades, Nigel White and myself is now available for purchase. Learning Ext JS 3.2 covers version 3.x of the Ext JS library and offers updated content and extra chapters since the first edition of the book. For new Ext JS developers, it'll give you a great starting point for working with the framework and enable you to create high-quality rich applications.
