Most of that stuff is covered, or at least I think it is in BE's helpfiles. The BE/EA helpfiles are frequently overlooked resources for information and knowledge. Spend some time in those helpfiles and I almost guarantee you that you'll learn a lot not only about the tools, but about tuning in general. At least, I did.
However if you want to get up a list of all your questions, I'll see if I can get them answered in a fairly generic way so they can be a Fast-track to learning the lingo kind of FAQ.
