Oh wow, I wasn't expecting responses so quickly!
Everyone has a point - I am definitely jumping the gun when it comes to making things up from scratch... Truthfully, I am pretty scared about all of the work, hehe. So, I'll keep that in consideration. (Note to self: Use a pre-made world first, work my way up).
As for the Dragon.. It is just a work in progress, but I was thinking that it would be more of a side-kick character. I have no intentions of having it take the spot-light whatsoever (I already know my friends wouldn't like that, lol). And by taking spot-light, I mean not letting it become an insanely powerful character. Even when it grows and gets bigger, it might still decide to not get involved in fights (since it's TN and all).
I figured that the Dragon would be an interesting plot twist.. Such as, the adventurers find it and decide to raise it, or if they don't decide to, the Dragon follows them anyway. Since my group is usually pretty morally-ambiguous (borderline evil, lol), I thought it would be interesting to throw them in such a situation where they actually have to think about the consequences of their actions - like how the little Dragon will be influenced by their actions, like how a child learns from it's parents.
I could use this Dragon to further the plot - like maybe people are after it, it's a connection to Gods, or something like that, but I guess I was just thinking about something like that to make it easier for me to make plot. ^^;;
If the Dragon shouldn't be the center of plot, I can have it be the center of a small sub-plot, see how that goes, and work from there.
And I don't usually have to worry about my character's being awesome, I'm not the greatest at maxing out my characters Dx
Thanks again to everyone for their advice and criticism!
