Welcome to Bleeping Computer.
As far as, "being in over your head", I wouldn't worry about that, too much.
BC is geared towards the novice user, so if there's anything you don't understand, don't be afraid to ask for clarification.
That's the only way, your going to learn.
Please take the time, to browse the New User Orientation
forum, to help familiarize yourself with how the board works.
If you have any questions about how to use this site, this forum will probably answer them.
Also, don't forget to check out the Tutorials
There's a lot of very useful information, in there.
