I'm pretty much self taught on acoustic. I don't claim to be a prodigy or anything, but I can generally pick up most things you here on the radio and such. Most of my learning came through a beginners guitar book, online tabs, and a friend that had been playing for a year or so and was at the time getting formal lessons.

What most other people said, get the basics down. Learn your open and bar chords. Just being able to switch through the major chords will get your fingers faster. After that you can start getting down some tasty licks. Ultimate-guitar.com is your friend for tabs, lessons, tips and such.
