hmm it seems that the book u got it trying to shove theory into you..imo beginners shudn dwell too much into theory as of yet...partly because of the excitement of wanting to learn a song they like and what not..i wud suggest learning basic chords first...have a feel for the guitar, build them calluses...till u get nice and comfy you'll know when ure ready for theory...tho its always a good thing to start on both in the beginning but i just reckon it tends to get pretty full on..my opinion..

and yea 5 bucks a month u really learn alot of stuff here...the vids are great... :)
