talks about various publications which one should familiarise with
I think this is the point you should be concentrating on. I think it's important that you should be able to know where to find information should you need it rather than have to learn everything parrot fashion.
As most of the content of these publications needs to be known primarily at the planning stage (ie on the ground), I'd say good familiarity with the location of detail is more important than knowing the detail itself.
A quick/speed read through the publications suggested will stand you in good stead for that lightbulb moment in the future "now exactly what was that rule about x/y/z?" Searchable pdf files really are useful in this respect.
