There is a book for that certification exam (but it's currently unavailable :(, no reason is given):
SharePoint 2010 Developer's Certification: Certification Toolkit for Exams 70-573 and 70-576
However, other books about sharepoint 2010 development are available. You can use these together with the
Microsoft Learning web site of the exam. In the "Skills Measured" tab you have an overview of what the exam is about. The combination of the books with the web site might help you out.
Professional SharePoint 2010 Development (Wrox Programmer to Programmer)
By Tom Rizzo, Reza Alirezaei, Jeff Fried, Paul Swider, Scot Hillier, Kenneth Schaefer
Inside Microsoft SharePoint 2010
By Ted Pattison, Andrew Connell, Scot Hillier, David Mann
Microsoft SharePoint 2010 Developer Reference
