Good advice from all. I think you just need to decide what tunes you want to learn that are within your reach, which is beginning/intermediate I'd think, find them and work until you can play them. Guitar is, after all, about making music and playing tunes/songs.
Try looking at these websites, find a couple books/dvd's/cd's that have the kind of thing you like, order it and launch ahead.

There are so many more resources available to learn from than there used to be, in any style you want to play. Lots of free stuff online, as well. But I think an instructional dvd geared toward the style you want to play, with arrangements included, is what you need. One book is less than the cost of a lesson from a bad teacher.
Good luck.
