how do you get better at guitar

I have been teaching myself and was more heavily into guitar when I was in my twenties. paranoid schizophrenia surfaced while I was deciding I wanted to pursue acting.
It didn't work out well.
I don't want to bore you with stories but I am beyond all the delusional rock star crap. I am 34 and I am studying business in college, finishing up while on disability. During the summers I want to get more heavy into my guitar playing.
I want to get good at recording instrumentals, I don't care if I have nothing to say but I want to get better at guitar, chord progression, songwriting. That's half the battle.
I am a big Elliott Smith fan, want to be able to have his skills or any skills , It doesn't necessarily have to be like elliott but I am suffering from mediocrity. I just want to holy grail for guitar skills. I ordered a Robert Johnson guitar licks DVD to study this summer while off of school. Not sure if delta blues will help.
If anyone can tell me a good book on songwriting or a good book on guitar scales, (because I only know my doh, ray me's.) Please do so, I feel maybe instructional video would be helpful as well because I am not the brightest knife in the bulb.
I have this crazy idea that after I graduate college , is to stay on my disability and go to Berkeley college of music and sneak around campus to find their curriculum on guitar playing.
Can someone help me achieve better knowledge of my instrument. I am desperate. Thanks
