1. Essential WPF by Chris Anderson
Chris was one of the Architects on WPF and therefore provides a lot of insight into why things were done the way they were. This book gives you the essence of what WPF is all about.
2. WPF Unleashed by Adam Nathan
Adam is an excellent writer and this all colour book is a real "how to" book; a book on how to get things done by using WPF.
3. Programming WPF by Chris Sells and Ian Griffiths
This is the deep dive on WPF, the nuts and bolts, the nitty gritty of how things work. This is a great book that I constantly find myself going back to.
