If your girlfriend has an abnormal pap and external warts she has both the high risk and the low risk forms of hpv. She needs to keep on top of her paps and get treatment if need be for that. The cream will only help the external warts. You have been exposed to it already (you may have even given it to her; there's no telling who gave it to who) and as long as you are only with each other you won't pass it back and forth. Once you have you have it. You may never show symptoms, or you may show symptoms days, months or even years later. Unfortunately condoms don't prevent hpv because it is a skin to skin virus and there are parts of you that are not covered by a condom. She may get them back after treatment or she may not ever have another outbreak. But there are plenty of other std's that condoms do prevent (as well as pregnancy) so you may want to think about that. Hope I was able to answer your questions. If there is anything else you need I'll try to help.
