Nothing wrong with self-teaching! It does help if you pick up a few instructional DVDs though. That way you can pick things up by seeing people play at least. There are some things that are pretty tricky to pick up by a description alone.
Probably the absoulte best written instruction you'll find is in the UK guitar magazine, Guitar Techniques. You can subscribe to it. Otherwise, I recommend Joe Satriani's Guitar Secrets book. Some of it is advanced, but there are plenty of things that are good for beginners as well. The good thing is that you won't outgrow it for years and years.
Eric Johnson has an instructional DVD called Total Electric Guitar, which is also very good. Just don't listen to him when he talks about his picking technique; it's appalling technique, though somehow it works very well for him.
Finally, there is another DVD called Fender Presents: Getting Started on Electric Guitar -- A Guide for Beginners and, although I haven't watched it myself, it's probably quite good to start with.
Have fun!
