I am in the same boat, I am trying to learn right now too. I originally started as a distraction when I quit smoking, then I kind of let is slide for awhile and I'm getting back into it now.
This is a pretty good free (donation) site with lots of good information:

If you've got a hundred and fifty bucks burning a hole in your pocket, I picked up the Steve Krenz Learn and Master Guitar course and it is EXCELLENT!!

It's a little excessive if all you want to do is play around a campfire, but if you want to take it seriously I don't think after researching it pretty heavily that you can beat that course.
Now, truth is all I want to do is play around a campfire, so the course is certainly excessive but I bought it for myself with some of the money I had saved myself by quitting smoking as a little reward, and I really didn't think $150 was that bad for it.
Good luck!
