First, if the C32 SC is like the 55ks, the SC is not engaged at idle so the noise in the video is not telling us much about the SC itself. Second, I just lost another clutch pack bearing and I can tell you it does make a chatter sort of like in the vid, but I don't think it was that loud. A telltale sign of a bad clutch pack bearing is blown out bearing race seal and usually a few of the little ***** are missing. Here is a pic. The seal or cover on your bearing looks fine.
I suggest you sit tight and wait for some good info from the guys on the boards. It will sure suck for you to replace the SC if it is not necessary. By the way, what are you calling the "BS" part?

sounds like your s/c pulley bearing.... take the belt off and spin all the pulleys by hand, one by one to find out which one is making the noise... if its the idler or tensioner pullies then its just easy bolt on replacement for under $100 used.... if its the main s/c pulley then you can replace the bearing and its a $80 diy job... i did mine a while ago and worked like a charm
you can also take the s/c pulley off the car and spin it in your hand as well to further verify that it is in fact the s/c bearing once you isolate that the noise is coming from that area and not the other pulleys
