DJM 2000 CDJ 2000 TRAKTOR 2 AND X1

Please could someone describe the cable configuration i need to hook this all up,  My mac has 2 usb imports but i have a total of four needing to go into it.  I also use a external hard drive so is it ok to put the DJM,CDJ, X1 into a hub and my external direct into the mac?  I want the cdjs to be config to djm  channels 1 and 4.

I also want remix decks on 2 and 3.  I have no idea what cables to route where.  please help me Obi Wan.......your my only help!

peace
