From what I have learned, as I have gone through this recently.....
You need the plug-in and an iphone. That should be it. The mocap is for the body and finger gear. The finger thing is not worth it IMO....
Use a network cable for best results, do not use wifi. It will work but it will be choppy or can be rather.....
Hope that helps. It's a nice add on. There is a really good video in the advanced section of the Reallusion training video section (Lost the link sorry)... The guy in the video goes into great detail on getting your iphone calibrated to your character.
Good luck...
