Hey Marty, first off I want to say your music is a true inspiration to me! My question is, does it matter how you play your guitar? Im left handed, but I play my guitar right handed. My left hand is much better at picking the guitar (I can barely pick fast with my right). Ive already been playing right handed for about three years now, and now when I try to play left handed, it feels way to unnatural. Will I be able to gain speed in my right hand for picking, or am I pretty much screwed?

No, in fact you were very smart in your decision to play righty, as there are millions more guitars to choose from when you have to buy a guitar. Lefties get stuck with the tiny amount that is available, or pay thru the nose for custom gtrs. Stick with it!
