What should I talk about with her of facebook that won't make her bored or make me creepy?

I'd say your best bet is to start talking about stuff that's going on with you. By the sounds of it, you've covered every question based trivia knowledge, so maybe next time you're talking to her, say "oh man, yesterday was the best because..." or something like that. The idea is to start talking about your day to day stuff, that way she'll get to know what you're like through what you experience, rather than just trivial information ie favourite bands and hobbies. Once you start that type of communication, your relationship should get easier and friendlier. good luck!
