Dear goodness your whole life story in one post.
Slow down mate you'll get there faster if you do.
Yes we have heard of the book, but that means nothing. This forum is about the Backtrac distro, yes it is based on ubuntu but it is not ubuntu in that you do need to know something about linux in order to get anywhere. Yes security is hard, yes you may be alone. Yes you may work on a top-secret or difficult project and be all alone in the world. Sometimes things like that happens.
Stick around and read the forums and then read some more. Read everything.
And then re-read it.
Also one thread per topic is generally the "norm" not as above.
Also if you have other questions then you better learn google-fu'
Not many people will spoon feed you.
