I don't think there is any drawback to waiting however long you're capable of waiting to let the fatheads and golden shiners to multiply before stocking your predators.
I mention the window of time between stocking bluegill and bass based on the bluegill's tendencies to get out of hand. But if your ultimate goal is large bass, that might just be exactly what you want them to do. They will not have the size of the bluegill and redears you see here on this forum, but your bass will have much more to eat. The kids should still have plenty of bluegill to catch, however, they will most likely be on the small side. Could wait for others to chime in and confirm this though.
Not sure about quantity of golden shiners commonly suggested. I don't believe it's an exact number, though, since the bass will likely hammer them into extinction over time. So I don't think you can make a mistake one way or the other.
I would think stocking your bass in the spring so they can get a solid season's headstart on that forage base would be a better idea than stocking them in the fall and having them go through a winter shortly after.
Again, yellow perch will need plenty of vegetative cover to avoid the bass. And walleye will need to be stocked in a way that they're not preyed upon either.
