If you are using mixed light then you would set the wite balance to the OTHER light source and compensate by putting the opposite gel over the flash... for instance flash with tungsten. You'd set WB to tungsten and put an orange gel over the flash to match the Tungsten lighting.
Or flash with NON-DAYLIGHT Flourescent tubes. You'd set the WB to flourescent and put a green gel over the flash.
(Check that you get good colour by shooting a some frames at the WB settings without flash first)
There's quite a bit out there on Nikon flashes by Joe MacNally (Speed of Light) and a lot of stuff on YouTube generally. Just go to youtube, type in your flash details and you'll get a whole lot of info.
