Great step to both of you! Also very cool to do it together as you both can help each other out. One suggestion is to find a great support system where you can ask questions, receive motivation and tips and have some fun too. Check out ours

Some quick tips to start out with are:
1) For the first two weeks, expect to be sore... A lot. After that your body will start to adjust.
2) Absolutely take your before photos. They are really great for showing your progress to yourself.
3) During the first 30 days, your weight may or may not change much. Some people it does and some it doesn't. There are a few factors for this. First is that your body composition is changing. You'll be adding muscle and losing fat. The second factor is that often times when you start intense workouts your body retains extra water. After about a month or so it stops and you'll feel like your losing a pound or two a day. I say this mostly in case this happens you won't think that you're doing something wrong or that the program isn't working. For me, the magic started around day 30.
The reason for that is also a bit of protective "swelling" and some irritation. Intense workouts break down muscle tissue, the body's natural response is swelling, one for protection, two for healing/rebuilding, three to flush out lactic acid built up during the activity.
4) Don't worry about keeping up with the people in the video. At first you probably won't be able to. MODIFY as needed.
5) Don't look at P90X as just a 90 day program. It's a lifetime program that you can do in 90 day cycles. It may take you more than 90 days to reach your goals, or even better,you may reach your goals and want to set a new one.
6) No matter what, keep pushing play.
