You do already know that she wants you to kiss her because of the text she sent you, so maybe it will come down to the timing now. You'll be nervous, like you said, but if the times comes on Friday when it seems as if you two are moving towards kissing each other, then I think you should try to go with it. If it doesn't happen immediately on Friday, I don't think you should be disappointed, it may happen further down the road. I think that you should only kiss her if you feel comfortable with yourself about doing it, not just because she told you she wants you to do it. As for being the perfect boyfriend for her, I don't really think there's such a thing as a perfect anything, but as long as you treat her right and with respect, you should be on the right track.
