I am very pleased with the Wrox books.
If you are work towards your MCITP: DBA certification, I would recommend picking up the Microsoft Press Training Kit, Set.
MCITP Self-Paced Training Kit (Exams 70-431, 70-443, 70-444): Microsoft SQL Server 2005 Database Administrator Core Requirements (Pro Certification) (DVD-ROM)
Since you already have the 40-731 book, you can get the other two books separately:
MCITP Self-Paced Training Kit (Exam 70-443): Designing a Database Server Infrastructure Using Microsoft SQL Server(TM) 2005 (Pro Certification) (Hardcover)
MCITP Self-Paced Training Kit (Exam 70-444): Optimizing and Maintaining a Database Administration Solution Using Microsoft SQL Server(TM) 2005 (Pro-Certification) (Hardcover)
I used the self-paced training kits and the Trancenders. I passed the 70-431 and 70-443 on the first sitting. I rushed my taking of the 70-444 exam, but passed with a very high score on the second sitting.
Your best reference is the SQL Server Books Online (BOL), use it, know it! All of the other material should be used to build on your foundation of knowledge.
Best of luck in your studies, keep us posted on your progress.
