I have this deeper in the thread, but I'll repeat myself: go take a good look at http://justinguitar.com/ He offers beginners [1] and intermediate course [2], technical stuff, jazz staff and much more. There you will also find recommendations on how to learn, what and how to practice. Justin has been teaching guitar for a long time so he knows what's important, what people struggle with and what to pay attention to. You will also find some songbooks for purchase and some free video lessons to accompany them. Highly recommended. No affiliation :)
