If you plan on buying wireless triggers, the best thing to use is a Hotshoe with Miniphone Jack from flashzebra. It enables you to use just about any flash with a wide variety of triggering devices. I personally use the product above with my Cybersyncs, and it's a great, reliable duo. The neat thing about the Hotshoe with Miniphone Jack is that flashzebra sells miniphone optical slaves that plug into the hotshoe so you can trigger your flashes optically as well (an optical trigger can be substantially cheaper than a 3rd/4th radio trigger).
