Hi,
I have to say Mikes book is great, so you won't go far wrong with that. It follows a similar format, going through the same information.
You also have many resources on the internet for the various parts of the system, so I wouldn't get too hung up on not having the actual 8912 info.
I took the exam a couple of years ago, and it's not to hard if you have a good working knowledge of the system.
