I use two bars for Kickbox Boot Camp (I think it's mis-named and should be Boxing Boot Camp because there's really no kicking in it at all). I use my bar from my Danskin barbell (6lbs) for the combat-style moves and then switch to a 12lb Bodybar for the rows and other standard weightlifting moves. How or why the same sized bar would be used for both cardio and weight work is beyond me!
Anyway, I really like Kimberly's camera presence. It was instant appeal, like Cathe (and Kelly Coffey-Meyer). Music on any of her workouts? I couldn't say, didn't notice. So it couldn't have been too great or too awful. Intensity.... I don't feel like I'm doing a whole lot in Kick Box Boot Camp, but I'm sweating buckets and don't know why. It just sneaks up on you. Cardio Camp - fun and different, but it's something that you get out of what you put into it. You can just go through the motions and not get much out of it, or give it your all and really have a sweatfest. It's not high impact, so that probably is why I feel that way.
