Work through my older GF2 course. It will explain all of those concepts.

Improvising looks cool to me and you tend to see many guitarists, who can just pick up a guitar and go into a whole lick pattern at random, I would like to be one of those guitarists.

Work through my collection of tutorials on improv. It will show you how & why.
