I'm having trouble with overexposing when using studio flash with nikon d800. Lights are Broncolour - not Nikon lights. Anyone have any idea of what settings might be out of whack to cause overexposure? Or recommend camera settings when using studio flash?? Thanks.

It really doesn't matter what kind of lights they are, studio lights are different than Nikon speedlights. They don't communicate with the camera to control the exposure.
But overexposure is always caused by the same thing- too much light hitting the sensor.
Plan A- I suggest that you get a light meter to sort this out. Then you'll learn a bit about settings.
Plan B- Shoot and adjust. Set ISO to 100. If too bright, step the aperture down (withing the limits of you desired depth of field) or increase the shutter speed until you get it right. You can also, presumably, dial down the power of the lights.
Plan C- Read a good book on lighting (there are lots), then implement Plan A or B.
So there are 4 things you can change to adjust the exposure: ISO, Aperture, Shutter Speed, light source. Depending on the subject and scene, one might be more appropriate than the other.
Welcome to Nikonians! Keep in mind that when using Manual flash units like the Broncolour Strobes you must use Manual exposure mode and Manual ISO. Also the cameras meter will only measure the ambient light level in the room and can not compensate for the additional light provided by the Strobe(s). Therefore you will need a Flash Meter or use the Trial and Error method to adjust the flash power based on the aperture that you prefer using the histogram. When using strobes, typically the ISO should be set to the base setting: ISO 100 (D800).
Broncolour Flash units do not support TTL flash control. They are 100% Manual.
If you are using the built - in Speedlight to trigger the Strobes via their optical slave, you should set it to Manual with the ratio at 1/128th power to minimize the built-in Speedlights contribution to the exposure.
Again you will have to use Manual exposure mode and adjust the flash power on the Strobe(s) as required to provide a correct exposure.
