My $.02: I would not mess with barefoot or minimalist running at this point. You're trying to get your feet under you (literally and figuratively) and messing with barefoot and minimalist right now, IMHO, is too much to take in.
I think the single most important thing to focus on at this point is shortening your stride. A number of things will likely (hopefully) happen as a result of doing this. You'll probably get more of a knee bend. "Run tall and lean from the ankles" is what many will say.
Give that a try. And what would be even better is, if you can do a video, do it outside. I think the treadmill changes the dynamics enough it may not be a good indicator of what is going on. (Unless, of course, you ONLY run on the treadmill and plan on doing the majority of your running that way.)
