Welcome to the forum. Thanks for your question.
The basic facts about genital HPV and its transmission have not changed in the past year or two. For a comprehensive discussion, see the thread linked below, from just a couple days ago; and the other thread linked in that discussion. I'll answer your specific questions very succinctly, but feel free with a brief follow-up is you remain uncertain after those responses plus the information in the other threads.

1) The genital HPV types are not know to be transmittee by kissing, French or otherwise. I can't say it's zero risk but it's certainly extremely low.
2) Genital HPV can be transmitted to a partner's oral cavity, but less efficiently than genital-to-genital transmission. Oral to genital transmission probably is rare.
3,4) These facts are true.
5) The primary recommendations are routine pap smears in women, which are most important over age 30; and immunization with Gardasil, the vaccine that protect against 4 of the most important HPV types.
6,8) In an ongoing partnership, the other partner can be assumed to be infected. A new partner is likely to be at risk, if s/he has not previously been vaccinated, or previously infected with the same HPV types causing the warts. But many couples conclude that genital wart just aren't serious enough to take any precautions. You should discuss it with your partner. If she and you decide it's important to avoid any possibility she will acquire warts, you have a few options: she can be vaccinated (understanding that protection isn't complete until after the third dose at 6 months); you can abstain until about 6 months after your warts have been treated (assuming warts don't recur in that time); and you can use condoms the next few months. Condoms aren't perfect, but would provide at least partial protection.
7) This also is true. The number of past sex partners is a poor predictor of the likelihood someone has (or has had) genital HPV.
I hope this has helped. Do look at the other threads.
