I would say your best bet is to read a book and experiment. Most basic photography books have "cheat sheets" with shutter speed and aperture settings. There was a book that I used in one of my basic photography classes called: "A Short Course In Photography." The Authors last name is London. That book has very detailed explanations of everything you need to know. Its relatively affordable at around $30.

Also, the lens you described is a Canon Digital Rebel lens right? The EF-S Is they type of mount and the 18-55 is the minimum and maximum focal length.

I use the wikipedia

In this time of the web people seem to forget that books still exists.
Time Life had a whole series of books on photography. One is called "The Camera". Everything how a camera works, aperture, shutter, lenses was described in it very clearly without getting too technical. Digital cameras still work according to the same principals old cameras do so you can learn a lot from this book. The whole series of photography is very good, there are many great photographs in these books and you also read a lot about the history of photography. Go to your library or try to find them second hand.
