Ok this is what I would do:
You seem like a fresh beginner at guitar. Therefore, you should learn many of your favorite song that are not too hard, yet challenging. Then once you develope a decent technique, start getting serious and hit the books.
When your fingers cannot even hold a string on the fretboard properly and your are learning 7 different chord progressions, its VERY tough.
So just make yourself comfortable at guitar and practice alot of tabs for the next month or so. Then when your become more of a fluid and better player, start learning theory so you can make up your own tunes.
