The wireless sensor is on the front of the flash. As the 360 FGZ doesn't have a swivel, there are going to be times when you can't position the flash so that it can receive the signal from the camera.
As the 360FGZ has an auto off mode that turns the flash off in three minutes in any mode except wireless, it makes it hard to overcome the positioning issue by also having a set of radio triggers as back up. For this same reason having a set of radio triggers to extend the shorter range of the camera's wireless is also hampered.
At this time the only P-TTL capable flashes that can disable their auto power off features are the, Pentax 540FGZ, the Metz 58 AF-1, and the Metz 48 AF-1.
Another issue to keep in mind with using the camera's wireless is that, when the camera is set to wireless, shake reduction is not available.
You should read the flash sticky and follow the link to Matt's flash guide to get an idea about the different P-TTL flashes and their capabilities. Picking a P-TTL flash for Pentax is like choosing between a van, a pickup truck, a car, and a motorcycle. Each will get you to work, but if you want to do more than that, then each has advantages and disadvantages that you probably will want to understand.
