You know, I dig your enthusiasm about playing the drums. And yeah, keeping a consistent tempo should be at the top of your list of things to do, as well as building up your coordination/chops a bit more, but really, that will come along in time. It's very cool that you have the advantage of video to see how you're doing and what you sound like - I didn't have that as a kid starting out. I'm assuming you know you don't sound like Keith Carlock or Dennis Chambers, but the fact that you're working on it is good - so don't stop that!
I'm assuming you're listening to the right players too, so if you know what you're aiming for, I'm not gonna beat you over the head about that, either. All I can really stress is the time thing - if you have a Dr. Beat or a drum machine that you can play along with, then you know you're playing in time. Maybe for now, go for simpler things to play, but do it in time.
I remember when Dave Weckl came out with his Contemporary Drummer + 1 book, I thought alot of that stuff was too hard. He later came out with a simpler book, and I used it on a few students, and they dug it! Back to basics playing in time - that's the name of the game. You're on the road - just avoid the potholes and you should be good. Have you found a teacher yet?
