I did my upgrade last night. Yes I did udate the Su binaries and Vodoo. I checked things after rebooting into JB. The Su icon was there, Vodoo was gone. This is where Batman's "recover root" comes into play. Worked Perfectly! Before throwing in the towel on root, give this a try.
Bt earpeice worked from the start. No calling problems, everything working as it should! Thanks Matt and all who help around here! 
My experience was better than yours, , went back to stock 181 using Matt's utility(did not clear data), updated the binaries (thanks to NiteWolf), double pumped on Voodoo OTA Rootkeeper, then flashed JB... Rebooted and came up without a hitch, and with root. However, Voodoo didn't show all the boxes checked at first, but now it does(go figure?).Either way didn't affect root permissions.(su works from terminal prompt and everything that needs root seems to work fine!)
Overall I really like the JB update! New Gallery is so much nicer and easier to use! Thankful to be done with MotoBlur, although do miss the music app with internet radio(obviously other apps around for that). Also love the updated status bar pull-down.
Battery life seems good so far, I think better than with ICS.
Very smooth overall, did find things are slightly better, especially in Quadrant if check "force GPU rendering" in the Debugging options.
Definitely needs to be "de-bloated".
Also seems better if set the sampling rate down to 50000 on the hotplug governor.. 100000 seems to be too often and interfere with scheduling. Set "up" threshold at 70 as well., "down" at 35.
Not sure if I'm a fan of the "auto turn on" feature for WiFi. Although have had no problem with WiFi or BT since the update.
Had to clear cache and data for a few apps to clean up some issues.
To people having troubles with root, did you also install the latest busybox before updating? I think Superuser has a minimal Busybox install, but recommends you downloading a full one.
Thanks again to Matt and everyone!
