Do I load, just my flats and dark flats into IP to create a Master Flat, not sure if IP will do that and then load my Lights, Darks and Master Flat to calibrate my Lights.
Any help with this matter would be greatly appreciated.

Median stack the dark flats and save it as masterflatdark.
Subtract the masterflatdark from each flat then median stack these frames.
To be more accurate each flat should be normalised (to an arbitary value that is near the average level of your flats) before the median stacking.
