I'm doing the same thing right now. There's really only about 4 techniques that you need to learn, on top of the scales. I'm learning two, alternate picking and legato picking. (do a search to find out what they are). Others would include sweep picking and economic picking, oh yeah and tapping.
It's just a matter of bringing your pinky into play, learning the minor scale patterns and then very slowly bringing it up to speed until you can play so fast nobody gives a crap what exactly you're playing.
