I couldn't help you with the questions pertaining hooking them up but I must say that I would honestly not recommend you go with a soft mat. I would take a wireless controller and make my own ddr mat, they last longer, are decently inexpensive to make, and not too difficult to do. If you do get really into ddr those soft mats will slide all over the place. Check out ddrfreak.com if you'd like to consider making your own.
