I've been playing for 22 years. I was blessed with a good ear, so I didn't "learn" theory, I learned patterns and how one string / fret combo sounds in relation to another. Ordinarily, I would not suggest this as a learning style, but it worked for me and it might work for you. Technically, I taught myself theory and committed it to muscle memory. I might be a lot better if I could have afforded lessons. Of course, I found Phish back in 1996 and Phish style improvisation (band plays music it hasn't practiced at a competent level, surprising the audience and the players at the same time) combined with a decent ear will get you pretty far.
My suggestions:
1) DON'T NEGLECT THE PINKY!!! Use it constantly. The pinky needs to be strong.
2) Pick confidently and in time. It may seem like your fret hand is doing most of the work, but you need to be paying attention to both hands simultaniously.
3) Start writing your own songs immediately. If you don't know how to play the sound that's in your head, move your fingers on the fret board until you find the root, then find the next note in the chord from there.
4) Beware of GAS (Gear Aquisition Syndrome). It's expensive:
Only a few things on this board cost less than $200.
