Learning guitar songs?

I've almost learned Sultans of Swing, one of my methods is to play the rhythm first and get a feel for that then slowly start to introduce the chops. This is usually by playing one bar or so at a time as you described. Then I'll start learning a different song and then come back to the song. Also there are some good lessons here a href="http://www.guitarlessonsguide.org" rel="nofollow"http://www.guitarlessonsguide.org/a
