See if there are any NRA certified instructors near you who are putting on a Basic Handgun class. An in person class with live instruction will always be better and more effective than just trying to get it all over the Internet.
And in any case, an absolutely great site for a beginner is
http://corneredcat.com/. It's directed toward women, but it's full of useful and authoritative information for any beginner (and every shooter, for that matter).
If you're going to try on YouTube, stick with the names g.willikers mentions in the preceding post. There are some absolutely God awful guys playing instructor on YouTube who have no idea what they are doing.
