When I first started to learn to play I got what I think is a pretty good intro from

Also, like other people said lessons can't be beat, If you can't get them hook up with a friend who knows how to play. I couldn't get lessons at first but my roommate played bass and just having him around helped a lot. Books and webpages are good resources, but you can't ask them questions. Also with an instructor they should be able to point you in the right direction for solid resources.
Another big tip, pick some easy songs to start with, take your time, and try not to get frustrated. Everyone learns at their own pace, by picking easy songs to play you notice your progress sooner because what you play will actually sound like something quicker. I think the best advice I've heard so far is from a sign on my instructor's door that reads "Think ten times, play once."
