The commander Pro has 2 RGB headers, plug the strips into one of them. The strips are daisiy chained, so connect in series, should come with extension cables as well. You'll only need the Lighting Node Pro if you add additional strips. For the lighting on the Fan to work, you'll need a Lighthing Hub (supports 6 fans), these usually come with the multi packs of fans.
My setup is Commander Pro, 2 lighting node pros (both plugged into the Commander Pro), feeding 12 strips, 2 Lighting hubs feeding 9 ML Pro RGB's. The lighting hubs connect to usb headers, so I added a Thermaltake H200 to additional headers, as my motherboard only has 2 headers and I need headers, for my AIO, wifi card and front panel.
