Introductions

I am a very noob songwriter.  I have 9 songs, which I feel need work. I am trying to study some theory, but it feels like I'm still playing by ear.  I can play a ton of chords, but don't really "branch out" with leads, because I don't know where to go from my chords.
I also need sheet music in my life (church uses a lot of it) and I would like to learn to play by looking at sheet.
