Oh wow. Thank you for all the amazing advice, everyone! ^.^
For now, I'm still going through the Code Academy things since they're totally free, and I figure that's the best way to learn if I really like it. But I did sign up on Neocities, and I'm looking at Udemy and Udacity. So far from what I've seen, they both look really good.
And I've started throwing down some ideas for a game, but... again, that's probably years away at this point.
