You will get different answers on that Sparrow question. That is because different things were done at different times.
If you are doing an early war USMC F-4B, then you can either put 4 Sparrows in their mounts, or just the front 2. Later on in the war, after a few mishaps and the discovery that the Sparrow wasn't that great anyway, just put 2 in the rear. There are stories of "don't ever put Sparrows in front of the Center tank",,,,,but, in Navair usage, those tanks were punched off before the wild maneuvering started anyway,,,,,,,so, you can just follow what your photos show and put 2 in the rear, 2 in the front, or all 4 on the aircraft.
I am sort of wondering how you are going to fill up 2 MERs and 2 TERs with one weapons set, though,,,,unless you bought more sets? (oops, just looked, 1 set gives you 12 500s and 6 500s with extensions, you have enough)
Early USN Sidewinders on the F-4B were the AIM-9B version that comes in your missile set.
