i personally do not think clubbing makes you 'SOOO' much more 'out there' as you seem to think. seriously, it is just a source of entertainment for people who like loud music and dancing. i do not think that the fact she clubs will damage your chances to be with her. i started clubbing at 16, most girls in my school, 15. but i will not turn down a guy simply because he doesn't club! there are sooo many more factors out there to consider when you are trying to decide whether a relationships with someone will work! soo....approach her, start a conversation...

good luck!
