Welcome to the place nobody wants to be at but it is a great place. Have you read MWD books DB and DR? That is our starting point and you need to read at least the DR book.
I am glad you found the courage to post so I won't hit you with any 2x4's just yet. But when you feel more confidant you can ask?
Some of the other threads have links to the resources and the detach link. Start with the detach link for now.
Sorry you are here but you will find a wealth of information and people on this board.
