Do I need a NMEA2000 starter kit??

I have installed the Raymarine es97 and although I haven't gotten all of the add on parts delivered yet I wanted to know if I need a starter kit for the nmea2k..

I have the T79 transducer, will be adding the Merc gateway with JBox for 2 motors, and the Rockford Fosgate PMX will also be tied into the Nmea2000 network..

Just trying to figure out if need a starter kit..

Thanks
