I'm kind of in the same boat. My technique is now up to par, but I've been putting off stuff like improvising and music theory. I always figured it would be best to wait to learn music theory until I had some technique. That way I could apply the music theory to some interesting licks, rather than just one slow note at a time, haha.

So I'm just beginning my music theory journey. I'm starting out by learning more chords, all my scales (major and minor for now), and the fretboard. There's actually a really good app (I think Guitar Tricks has their own version too) that teaches you the fretboard. I have one for my iPad that works really well called Fret Tester.
