DG, I am also self taught. You've already done the best thing you can do by signing on to Chordie! All good advice above. Play every chance you get. I was impatient and jumped to just chords and now I wish I spent more time on scales been playin 3 years now and am going back to get my scales down as you get better you'll want to know them. As for an easy song try just the begining of American Pie there are alot of chord changes but it's slow and simple (gets your fingers movin) and you'll recognize it right away helped me.
