Answer 1

I can tell you from personal experience that it is extraordinarily difficult to write a technical book with zero defects. Spell-checkers and grammar checkers produce huge numbers of false positives when looking for standard (i.e. non technical) errors. Technical errors are easy to introduce -- forget to add a 'Not' in a sentence, or something similar -- and hard to detect afterward. When I read through my study guides looking for errors, I tend to see what I meant to write.
That said, such defects are normally a tiny fraction of the information contained within certification manuals. A couple of reviews on the Oracle Press 1Z0-052 book written by John Watson mention a couple of errors and then imply the book is filled with more. I've read the book and it is very informative. It contains hundreds of pieces of information and contains about ten errors -- all mentioned in the errata on the McGraw Hill site. The books is good preparation for the text and for learning the basics of being an Oracle DBA.
As Aman indicated, using more than one source is a good way to help to detect inaccuracies. I believe in always using multiple sources and the documentation is generally a good option for that.
