I./JG54 Jagdgewaffe structre help!

So I am creating an online unit for the upcoming game IL-2: Battle of Stalingrad. My unit is I./JG54 and I am unsure of it's structure and camo schemes used during that war. I am also unsure if all planes had outlined numbers or just the high ranking pilots?

I have attached an image for review. Can anyone please help me or direct me to a book that has this kind of information.
