Without flash I suggest you read your manual about continuous shooting (I think that it is available in all positions of the mode dial, and set using the button to the right of the LCD that looks like three overlapping book pages) and turn off noise reduction - your manual will inform you of how to do this. In general shooting in jpg mode will yield faster, longer bursts of photos than shooting in RAW.
With flash the camera will only shoot as fast as the flash can recharge - even with a powerful external flash this can be several seconds between shots. With the small internal flash on the D80, expect to wait between 0.5 and 2 seconds between frames in any mode.
Otherwise the settings for with and without flash will be the same.
