Dave,
Nooo, don't be confused! The easiest way to think about it is to treat your flat frames just like light frames. You take darks for lights, so take equal length exposures for your flat lights.
Some people will tell you to take bias or offset frames to remove sensor readout noise (1/4000 or 1/8000 second exposures, the shortest your camera can do), but, in my experience they tend to ruin or add artefacting to my images. I also figure that the bias is also recorded in the dark frame, so, shouldn't really need it. Might work for others, just not for me!
Hope that helps.
Regards,
Humayun
