Hi Soulstress,
I've played keyboards, drums, and guitar professionally, and have studied music theory for years when I was young; I even majored in college in music theory for a time.
On your question about theory, I'd say just learn the basics -- what the chords are in a Major Key (they will either be major or minor chords) and slowly over time learn what the relationships of these chords in the key are to each other (e.g., start with: I, IV, V).
While doing this, continue to learn how to play basic chords as well as how to play the Blues Scale. This way, in a short time you should be able to play not only chords with songs but some lead as well.
Stay busy, balanced, and keep trying to get better. Theory has its place in guitar playing, but more importantly is learning the guitar is a lot of work, and all this work is play, and all playing is fun!
Let your ears be your guide and best of luck!

I was taught to think the next week or month or year will only get better than it is today. So I just keep waiting to see how great it will get! --- Stevie Ray Vaughan
