Pretty good that you've got so many ideas after such a short time playing man well done, I would say tho cus its metal you wana play (THANK GOD :d) you should be spending pretty much all your time developing lead technique and learning the standard guitar theory (natural minor/maj + pentatoinic minor/maj) even if you just wana be a rythm player! Also learn to play the blues lead!!! important!

Keep on working on it man! good stuff
