I agree with Razbo, It depends on your interests, I think at the beginning stage The most important thing to learn is Chord Shapes, Chord Changing, and Keeping time to a metronome. That should take your mind off reading music for awhile.If you are planning on becoming a Professional Musician, Session guitarist, or Songwriter for hire, than it would be important to learn to read. But focusing on the chord shapes and changes as well as keeping time will give you the quickest results. Tab is everywhere and easy to understand.
