It states in the Cyber Sync info that they ship with several sync cords so you should have everything you need to at least use your Sb800 speedlights with your csrb's. The SB800 has a pc sync port which will connect to your Cyber sync via the "1/8" to pc sync cord" supplied with your csrb's. For the SB600 you will have to buy a "hotshoe to 1/8" plug" like this product from Flash Zebra since I do not believe the SB600 has a PC sync port (I am a Canon shooter so my first hand knowledge of Nikons is limited):
