The SmartConsole help is extremely rich, context-sensitive, and very much underrated as a source for information. Of course the CCSA/CCSE training will help along with the formal check Point documentation covering management.
I will also say that there is an independently-produced book currently being written that is not just about the SmartConsole but does cover it heavily. While the Check Point documentation is excellent, sometimes it can be helpful to look at the Check Point product from a different author's perspective. I am not directly involved with this new book but have given its author some informal advice; I assume there will be an announcement at CheckMates when the book is released so stay tuned!
