Well, let me get this out of the way first: I'm not promising optimism here. I wish I could say I was, but, well....
Do you know if she's single? That's important. If not, then option 1 is even easier. If she's not available then it wouldn't go anywhere. If the answer is no, and she is single, consider this, and I'm not bringing up any of these points with the intention of being all "You too young, boy, you gotta grow up more first," just to bring some things up that she might consider.
Is she living with her parents or not? If she's out on her own, the whole living with parents thing (regardless of your age) likely won't go well.
She's five years your senior, that's a fact of life. My guess (and it is only a guess, accuracy not guaranteed to any percentage) is that if you do take some next step, she will likely be flattered, and think it is "cute." That's right, the dreaded "cute" word. And probably more the puppy dog cute than anything else. Just be aware of that if you haven't thought of it already.
Past that, well, the best way to get past her is to take the next step and get rejected. If you take the next step and aren't rejected, then you don't have to get past her. As for what to do? Uh...sorry... I don't have the slightest idea. Hopefully this has been more than an insomnia-fueled ramble session.
