Need Help Directing Effort.

Been playing three years now. I enjoy learning music theory and have been studying the Modern Method for Guitar book and JustinGuitar's program. I have learned a lot of stuff but the attached video is where I'd like to be, albeit in 20 years. I have basically been learning the guitar through Jazz and Acoustic lessons when I really want to be playing metal. Any comrades have recommendations on a course/book/pathway to concentrate my efforts? Thank you.

P.S. I really dislike the singing in the vid but the guitar is awesome.
