Understanding Abnormal Pap Smears in Teenagers: What You Need to Know

Question
My 15 year old step daughter had an abnormal pap, she was told to come back in three months to have another, which she did.
On this last one the pap was different, instead of a slide they used liquid. (I believe this was the difference)
Anyway it came back atypical Squamous of the unknown.  Can not rule out high grade intrapelal (sp?) lesion.
I looked this up on the internet and it said that is caused by hpv or genital warts.
I have three questions :
1. Is HPV or genital warts the ONLY cause of this squamous.
2. Is this something we can catch from her through casual contact?
3. This is a cancer? Or a precancer?
She is scheduled for a consult with the Dr. next week and she is going to have to have a biopsy.
Thanks.
