1) Judy Nall's book was the latest to publish and I've been told it is selling VERY well! I hope those who are purchasing the book are taking and passing exam 737 as a result!
2) Susan Lawson and Dan Luksetich are beginning to update their Certification Guide and hope to have the new version of the book to match the new exam by IDUG in May 2011.
3) Roger Sanders is in discussions with the publisher to create a V9.7 update to his very popular V9 Cert Guides.
To prepare yourself to pass the exams read through a previous blog entry that I did called Certification 101.
Buy or borrow a Study Guide related to the exam you are taking. These books are available electronically through Books 24x7 or Safari Books Online. The suggested books are:

Susan Lawson and Daniel Luksetich
DB2 9 Advanced Database Administration Certification Study Guide for Exam 734

Note that all of these books were written by members of the exam development team and each chapter contains sample questions along with answers and explanations.
