Break out your records (CD's to you young whippersnapppers) and learn, learn learn.
Learn the bass parts, the guitar parts, do air drums, put headphones on an listen to the mix and how it's put together.
Then spend time learning the basic scales and rock scales so you know how the leads are strung together.

There's no detailed path to learning.... everybody does it differently.
I spent the first 5 years playing with only 4 strings tuned to an open G and even after learning how to tune properly I didn't stick to any practice schedule.
When I was a teen I just left my guitar out and plugged in all the time and got my practice whenever my dad would should 'GO TO YOUR ROOM'

He figured it was some kinda punishment but there was nothin else to do so I learned guitar.

(I also recorded myself so that I could play it back and sneak out the bedroom window and he'd think I was still in there, but that's another story :)
