Watch the Reading Chord Charts online guitar lesson by Bruce Arnold from Jazz Guitar for Beginners
Reading a chord chart is a very valuable skill. It will help you save time when learning music and give you the added ability to walk in cold to a rehearsal and play a song from a chart. If you could read a chord chart once a day it would make a major difference in your ability over time.
To help you with reading chords I suggest working with the "New York Guitar Method."
This series of books has sight reading chord charts and melodies throughout each book that gradually get more difficult.
