Welcome to the forum.
You are correct, it is a very expansive library of great information, and it will take years to read it all -unless you read 24 hours a day, 7 days a week.
You should check out the library section, as well as download Hoke's books - they are our definitive go to guide (as well as the goodies in the library)
A few members have links in their signatures - visit them, they are all good stuff
