BB, if you're keen on folk music then I suggest getting the Russ Shipton series of guitar tutor books. They're set at a reasonable pace, and basically take you through everything you need to know to play folk guitar. And they've got a fairly good selection of folky songs in them too. Make sure you get the basic "guitar tutor" ones and not the "rock guitar tutor" ones (which often teach bad techniques that you just happen to be able to get away with on an electric with ultra-light strings).
