No problem! It was a bit more verbose than I normally would do, but it sounded like you were a bit overwhelmed, so despite the fact that most of what I told you is a quick search away, I figured that pointing you to Google wouldn't be very helpful. I was just trying to give you a kickstart, so you can start fiddling with things and learning right away. If you have questions about Ubuntu or Linux in general, then ubuntuforums.org or linuxquestions.org are probably more appropriate places to ask them, but if you have anything else to ask in the same vein as your initial questions, post them here and I'll do my best.
Cheers
