I would never get anything pierced myself, but ears and navel are a must for me on girls.
Nose can look cute, too, and I once dated a girl with a pierced tongue - never thought that was quite as good as it's cracked up to be, though...

If a girl would like to have 1-3 standard sized earings in her ears thats fine. A belly button ring is also fine. If she would like her genitals pierced thats fine too. However I do not thing it is attraxctive to see girls with any bars or nose or lip pierccings a tongue ring is alright.
Guys. You should leave the earings for the ladies.
