Beginning Guitar Advice

Yo, I am a drummer beginning to play guitar to have more atanomy in the song writing process with my buds. I am starting by learning all the blues keys and the major chords within them, then rocking out some cool progressions. Also, I am pretty schooled in music (piano for like four years), so theory is no problemo, just getting my hands use to where the notes are on the guitar. Do any of you guys have any suggestions in learning guitar to help write songs with bands?
