Open with I'm pretty rad... and you're totally spiffy."
Are any of the authors, music artist or movies that she's listed ones you like? Talk about that... and ask her to tell you about the ones she likes that you don't know. People like to spread the word.
You read a lot, and you've got ...interesting taste in music. Tell her about that.
Be self-deprecating (but not TOO much, don't put yourself down)...
Be funny.
If you've got no pic on your profile, send her one. I've heard from reliable sources that you're good looking. Lose your fear.
And remember:
If you don't play, you can't win. The worst she can do is say "no".
