Access 2007 Offline Help File/In depth help

So, just about every post I see on here, where there is a question about a function etc, I see at least one reply that says 'The help file contains a ton of great info'. I get that, but with that,  when I am coding in VBA and I type say 'Application.' and then the (I forgot the name of it) intuitive drop down box appears and there is a list of things you can select with the Application function. I want to know how you find out what all those types of things mean/do. I am not limiting it to the Application. function, I mean all that kind of stuff. Help is somewhat good at that, but where can I find out the in depth kind of stuff.

I have SEVERAL books on VBA - Bibles, Programmers Guides, etc. Is there a 'COMPLETE' book out there somewhere? I have a feeling there are some very cool things I could be doing, or things I could do better. I just don't know how.

Would this be more of a Visual Basic book that I need to reference?

Thanks for ANY websites, books, or info you can steer me towards in my quest for mastering Access. : )
