WOW! I think how I started was a great way. I ignored theory and just learned how to read tab (takes minutes), then I just started learning small simple pieces my favourite bands played. Start enjoying the music first! If you play it that way you dont really have to learn theory... because... if you learn how your favourite guitarists plays then you are inadvertantly learning scales and tricks that youd otherwise be boringly reading in a book!
My advice is to find a guitar hero!
