Glad to hear you are learning and making progress. I have a similer story about how I got into BackTrack. I just switched my major from political science to computer science and I took a network security class because it sounded fun. A friend in my class used backtrack to test some of the security measures I put in place on a system I was working on and I asked if I could copy his live CD.
Well once I stuck that thing in my drive I never looked back BackTrack is a wonderful tool for what it was designed to do, but is also great for exploring the world of linux and seeing how computers really work. In my opinion its the LACK OF user friendliness that makes BackTrack such an awsome learning tool. I know that after only about 2 months using it that I am still a newb, but it got me to be comfortable with command line and I also have the satisfaction of knowing that if I can get something to work on BackTrack it cant be any harder on another distro.
Basically, if you are more challenged by problems than intimidated then BackTrack is great. If you are looking for easy, go get a copy on winblows.
