^^I agree with Buster about learning the notes on the fretboard. It's not that difficult
once you understand how the notes are laid out. First memorize the notes on the low "E" string
(or even the notes that are at the dotted frets, most guitars have a dot at the 3rd, 5th, 7th 9th and 12th frets)
Then the "A" string.
Also, a guy named Mike Dodge has a web page dedicated to learning the notes, as well as learning the
basics, I think it's Mikedodge.com. He does it in a very straightforward and easy to understand manner.
I recommend it to all of my students.
Hope that helps.
