Like stated above regardless you must attend a Class to obtain your VCP certification. Mastering vSphere by Scott Lowe is a great resource and will surely help. And personally I would see that as a reference manual over study guide.
There are other books out there
VCP Exam Cram
VCP VMware Certified Professional vSphere 4 Study Guide (Exam VCP410)
Both are great resources geared towards the exams.
