It's funny, I have the reverse question about the shy guy I like. I'm not sure what creates the static chemistry between people when they like each other. I used to be shy and had to get over it quickly because of a personal circumstance. I had to just take a deep breath, put it into my head that I would speak up, and just get over myself. While I'm still a little shy in specific situations, I'm not generally afraid to tell people how I feel, ask people for what I need, etc. unless I'm having questions/reservations about speaking to a person. That's more a matter of examining the big picture than it is about still being shy.
My point is that perhaps the shy awkward stuff is the testing phase. If you feel you're past the testing phase, just pull together a few ice breakers -- unusual phrases or questions designed to get her laughing so you two can bond, chat, etc. The aim is to get her to smile/laugh at you -- and when she does, to smile and maintain eye contact with her. In other words, take your deep breath and just jump in. The best that will come of it is love, the worst...experience. :-)
Common sense and years of experience....
