Replying to Experienced Guitarists Gather

So I've been playing guitar for about a year and a half, teaching myself. I played piano and took lessons for 8 years, so I know there's more to music than just memorizing chords. SO NS, my question is where to go with guitar. I really wanna get into theory/improv/soloing/pentatonics etc. WHERE DO I START? I know all chords barre and open, and understand the basics of how a guitar neck is laid out musically. Also I have been learning a few basic scales, but can anyone give me a nudge in the right direction to kick start my next couple challenges.
I have been learning more "intense" songs IE little wing, yellow ledbetter, pride and joy etc.
