This page (http://www.ashastd.org/hpv/hpv_learn_warts.cfm) from the American Social Health Association may be a good place to start for answers. As far as I know (disclaimer: I am by no means an expert), HPV isn't like passing a bacterial or yeast infection back and forth. If you both have it, even subclinically, then you both have it. But I'm absolutely going to defer to anyone who can find an authoritative source on this.
As for your second question, the ASHA says this, "Warts are not commonly found in the mouth, so some experts believe that transmission through oral sex is not as likely as with genital-to-genital or genital-to-anal contact." Generally speaking, different strains of HPV have "preferred" locations on the body. If your particular wart strain is comfy in the genitals, this decreases the chances that it will want to hang out in anyone's mouth.
