Well, I can't confirm the material in the book, since I don't have the cert library, but the other 4 book set.
I'll give you some clues for the switching exam:
The exam you want to register for and take is 640-604
(CCNP Switching).
The passing score is 776, you will get approximately 58
questions (I scored 877).
The exam is heavy duty into IGMP/CGMP/Multicasting/MLS/
and product selection and placement in the 3 layer cisco
network model (core, distribution, and access).
The exam has a few gimmies (cabling, etc), but is a fair exam. Other questions you might see are HSRP, STP/VLAN's,
Trunking (including VTP), and you should know how to convert a Multicast MAC address into a Multicast IP address.
In addition, make sure you KNOW the differences between set based and IOS based switches (testable models could be 19xx/28xx/29xx/35xx/4xxx/5xxx/6xxx/7xxx/8xxx).
Good Luck
