You're both shy, likely both new to relationships, so you really don't have to worry about rushing things. Hold hands when you feel it's the right moment, without allowing yourself to worry too much about whether or not you'll scare her or make her uncomfortable. Of course it's important to keep that in mind, but it's just as important to do what you feel is right. Don't allow her to make all the choices though, a relationship goes both ways. If you're really worried about pushing things, or making her feel uncomfortable, talk to her. Communication is another important thing to keep in mind and practice within a relationship. If you want to kiss her, but you're too worried about pushing her that you don't, why not ask her? Perhaps she'll momentarily feel embarrassed or shy, but if you can't bring yourself to kiss her without asking, you have nothing to lose. If neither of you make a move in this department, nothing will ever happen. It's entirely possible that you'll find yourselves in a relationship that more closely resembles a friendship if neither of you make any moves.
Don't allow yourself to think too much when it comes to doing anything with her though, otherwise you may end up doing it in a much more awkward or robotic fashion than if you had just gone with your instinct. Spend time with her, get to know her, and do whatever feels right.
