Good job man. Park Tool has repair instructions on about everything in the world.

OK, a couple of rules you must follow as a cyclist:
Never turn you bike upside down like that. It is disrespectful to your bike and it's a rookie mistake. A repair stand is mandatory but for now, just try to hold it upright as you work on it.
Never say some one adjusted you front wheel when you are talking about your front derail...
The most import one is HTFU. You will learn that one and once you do, there is never a reason to skip a ride.
