Being rich enough to afford guitar lessons, and actually studying at the "conversatorium" (a very high music school after high school) I got a few tips:
1. TABS ISNT ENOUGH. Try to learn the g-clef. If you really want to go pro with guitar instead of a hobby, learn the c- and f-clef also.
2. Learn the right fingerplacements. Doing this will help you greatly, as all songs basicly use chords, or part of chords (like some song only use D and F# from the standard D-chord), having the right fingerplacement can help you with alot of songs, so that way you won't get your fingers in a knot when you get to higher level
3. Learn the basics of music, and making music. Knowing what a crescendo is might not seem important, but everybody that ever touched a musical instrument probably knows this kind of stuff. Basic knowledge and understanding of music can help you get better and make sweet music.
But it is up to you how much you want to do with music. If you want to go pro, you really need to get a teacher, or buy books about the mechanics of music. If you just want to dot his as a hobby, you must see for yourself how casual you want to keep it.
Edit: But most of all, have fun with it, because that is what music is about
