A good 10 min warm up before the weights, and 15 min cooldown (low intensity) will not hurt your progress. Save the hard cardio for days you don't lift.
Actually the cool down at the end helps the vascular system.

Still trying to find out how to do the Hollywood Free Press.
Carivan's right. It really doesn't interfere that much. If you're on a high rep/low weight program along w/ a diet control, 15-20 mins of cardio helps keep your target heart rate up, and you burn a little more. And you can really do alot more on your non-lifting/rest cycle days. Just watch your calorie/carb intake to make sure your balanced. Hope this helps!
