The PS Move controllers are optional...you'll want them to record wrist rotation and/or head rotation, but they're not required for body capture. To use them, you'll also need a BT controller, but one BT controller should work for multiple Move controllers. Normally the BT controller is a dongle attached to a USB cable, so it may require another USB port. But if you're laptop has built-in BT, you don't need the extra cable or dongle.
My typical setup is two Kinect v2 sensors (aka 'Kinect One'--sigh, don't ask,) and three Move Controllers. Because I'm using the newer Kinect v2 sensors, I need to use two computers. My workstation is the master computer and has 1 Kinect attached to it; my tablet computer has the other Kinect attached. The tablet has built-in BT, so I use that for the three Move controllers.
I hold a Move in each hand to record the wrist rotations, and have a third velcro strapped to a helmet. To operate Recorder, I use the buttons on one of the Moves as a remote.
There are some pics of the helmet on my website:
http://littlegreendog.com/?s=mocap+helmetMocap Studio can generate head motion without the Move controller--in fact, you may want to keyframe the head rotations even if you have captured head motion because your character will need to look at specific things in your final scenes anyways. (The same might be said for the wrist orientations.)
If you don't use the Moves, you'll need to keyframe the wrist motions. IMO, it is nice to have the recorded head and wrist motions--it makes the motion look a lot more natural--but it's not difficult to keyframe wrist animation either.
I'm planning to create a bunch of 'how to' articles this summer, which will include iPi Mocap workflows. The iPi article is likely to be Kinect v2-based since that's what I mainly use nowadays but the workflow and gear is mostly the same with other cameras. I have experience with PS Eye, Logitech web cameras, Kinect for Xbox, Kinect for Windows, and Kinect One, so I'll explain the differences with these in the articles. Will make an announcement when that happens.
But in the meantime, all this info is described in the Wiki and manuals. I would highly recommend going through the documents. There's also a lot of useful info in this forum by other iPi Mocap Studio users and the iPi staff.
Feel free to keep asking questions here though.
Hope this helps.
