It sounds like you can skip the guitar fundamentals and go straight to Rock Level 1 or Blues Level 1. Just start from one end and work your way up lesson by lesson. Really take the time to work on the material. There might be some stuff in there that you already know, and in that case just skip it or re-work it.
After you have a basic understanding of blues and/or rock, you can branch out a little more. You mentioned an interest in many different styles of music, but in my experience it's very important to have a basic understanding of rock and blues before you start exploring jazz for example.
Let me know if you have any questions. God fornoejelse!
