Man oh man! You can never go wrong with bang it just to bang it! But seriously……. i really dont see why her having “hooked” up with your friend would be a hang up unless it is some sort of indication of a character flaw or something. I mean hookups happen and it doesnt sound like it was a serious thing so…. If you dig this chick and she is game man, take her out and go have some fun.You will probably regret it if you don't. Don't over think it.

Just do the damn thing man!!!!
