I suggest a completely different way. Forget more that three-finger chords. Powerchords are ok for a start, but quickly move away from that. Learn alternate picking very very soon. I mean, select a string, and a note and learn to go up down on the pick on it until you're very fast and you can go from string to string. Then do this up an down thing while going through chromatic scales (chromatic meaning, go from every fret to the next fret to the next, etc) up and down. Then stard doing chromatics by skipping every other string. You should learn scales later on, when your hands are pretty used to being coordinated with each other and your fingers 'know' how to voice fret runs.
