anywho, I recommend a book called Guitar Method by Hal Leonard, actually there are 3 books (1 - 2 - 3 by order of difficulty.) or you can buy the spiral "teachers edition" (ok i know its not called that) it has well placed diagrams and easy to learn instructions.

also for speed-accuracy practice, after you've done a few exercises in the book of course, try playing scales. they may be boring but they do work.
