You are really complicating things, its really not that hard. You say see doesn't know who you are, I believe that, I don't believe she "kinda likes you," if she doesn't know you, how can she like you?

Just start talking to her. Ask her when and where ever you get a chance, and do it as soon as possible and don't hesitate when you do it. When you see her, ask her how her day/weekend/etc was. And keep the mentality you are just asking to find out how her day /weekend/etc was. Simple. From there ask her about her day, tell a little bit about yours when she asks, embellish any story a bit to make it more funny

Don't start flirting right away, just get to know her better. If you can open your mouth to her, then you can make some jokes, a neg or two, but just show her how you are a fun and cool person.

Just have fun, be relaxed and don't sweat it too much. Talking a girl is not the hard part. Asking her out isn't the part. The hard part is finding time in between school, work and other random shit to make room for her. You know you found the one when she fits perfectly with your life.
