What key am I playing in here?

Working on a new song and I have the first two parts that I began with....I've added alot more, but the song feels like it's going in two different directions now, and I feel I have to reel it back a bit. So, it could go two different way now, and I'm really not sure which way I want to go now...what I really would like to know is: What key am I playing in here?

I found this article online, but can't understand it at all, as I know zilch about music theory, or notes, or anything:

I want to know what key I am in because there's another article that talks about the 7 chords that work with whatever key you're in:

Can someone tell me an easy way to figure this out...and finding the 7 chords as well. I think this would be a huge help in getting this song written well.

Thanks Todd. That's alot to digest for my non-musical theory thinking mind, LOL. I'm gonna have to read this post over and over again, because it's just not sinking in yet...I'm just not getting it. This reminds me of math, and it was my worst subject...which is odd because I'm great at keeping rhythm (time). I've been thinking lately of taking CBG lessons from a guy about 25 miles away from me. He's a guitar teacher, and he also makes, builds, and plays CBG's. We talked previously, but he gave me the impression he doesn't play his CBG in the standard tuning I am familiar with (namely GDG), and had mentioned some other odd tuning. I guess I'm hesitant because I'm not sure what he intends on teaching me (he plays in a classic rock band on the side). I'm getting up to speed with moving around the neck, and finally sounding a bit musical now, so maybe I should seek some lessons at this point. That way I can pick the teachers brain when we meet, and maybe makes some sense of this stuff.
