I think your boyfriend especially will find that he wants heavier weights than that pretty quickly. I'm a girl and I use 15-20 pounds for most of the exercises in P90X. I've been doing it for a long time now, but even when I started I was using 10-15 pound weights. It depends on the strength you've already built up, but don't be afraid of going heavy.
The program isn't really set up to be done just once a week, though. You work different muscle groups in each strength training video and it's important to work all of them regularly. My sister and I do the three weight workouts on Mondays, Wednesdays, and Saturdays, and then substitute our own cardio/yoga the rest of the week on our own.
