Ok. I Didn’t read most of this thread, also my grammar is terrrrrible. But hope I can be of help.
Green Day and Nirvana, in my opinion, are no good. Listen and learn if you want but you want progress too much from them. My friend CroG here says that getting into metal will be helpful, and as a huge metal fan I will say there are some very technical riffs out there, if you really want to be impressed listen to Necrophagist, you may not like them but technically they are INCREDIBLE.
So, what if you don’t want to play metal? There are plenty of other virtuosos out there. Allan Holdsworth is a great Jazz Fusion player. Chris Broderick, (though primarily a shredder) has mastered classical guitar, jazz slap etc etc. Classical and Jazz/Jazz Fusion is filled with great technical parts. Paganini, though I haven’t heard much of, is fantastic and a lot of guitar players are inspired from this violinist.
My point is check out some musicians that really inspire you.
The main reason I say this is because there are too many styles today that can hold an entire career with power chords. Don’t settle for mediocrity.
Moving onto actual playing though, I would say get into theory (scales, keys etc etc) as early as you can (a mistake I made). But don’t start off in it or it will probably bore you. In all honesty, many musicians write and play brilliantly will basically no theory knowledge BUT they have an ear that will destroy most musicians. Even if you have have perfect pitch you still need some basic theory, trust me, you will get basically no where without at least being able to tell what notes are in key, how do you do that? Scales.
I cant say the word enough SCALES! It’s actually something I need work on, one can never know enough scales but you can make perfectly fine music with just 3. maybe 4 scales.
Major.
Minor.
Harmonic Minor.
Melodic Minor.
4 Scales, and honestly Harmonic Minor is only 1 note difference from Natural Minor. Melodic is rarely used but it won’t hurt to know it right (even i should learn it better).
So once you get scales down you will found you have come a long way.
My point is…it is work.

There aren’t any shortcuts. It almost seems liek you might be asking for them, that isn’t a cut, I find myself doing the same things. I often look for lessons on songs difficult parts thinking it will magically make me be able to play them.
It doesn’t work that way.
In a single sentence this post is. “Learn scales and challenging music.” But also have fun with it.
