How to advance from newbie to god?

I have a simple question,

I am as I stated at some other point a newbie, I have played for less than a year and my "effective" playing time is probably less than three months I guess.

I am doing some scales just to get my fingers trained and to learn coordination. I also play some tunes with chords.

Now to the question. How do I advance from doing scales. I play some "solos" (Slash/Knocking on heavens door for instance) to just to have fun and actually learn one or two tunes. But from that I feel that I just sit and stare.

Should I do more scales, arpeggios. I mean, how did most of you learn to play. Probably not by just playing scales I guess ;-). I know that I could be better just playing the solos but I feel that I need to get up to a certain level before advance to the real stuff.

This may be categorized as philosofical, maybe I am just eager to play more and better fast but it would be nice to know the steps to take from here on.

Questions about theory and practise

Two questions:

How much should I focus on the theory compared to playing the guitar?

Right now my biggest problem (well, I AM getting better at it) is that my fingers dont always end up where they should on the string that is played and of course the tone doesnt sound right then. Is there some "good" way of training this?
