To anyone looking to learn guitar at home I highly recommend lessons offered by Desi Serna. He does a fantastic job at presenting a well planned lesson format for all levels of guitar experience and all at a reasonable price. In most cases, theory of any type can potentially be boring. But I find his materials adequately combine theory with popular and recognizable music to make learning fun.
Here is the link to his website: http://Guitar-Music-Theory.com
Enjoy!
