IME, 78 is the number to shoot for. I can think of some corals that will start to melt down if they push 82. Euphyllia, Xenia don't like it, for starters.
It's going to be hard to observe 'schooling' in a tank of that size, Bill. Chromis aren't a true schooling fish but they (and others) do sort of shoal together.
4 shrimp seems like a lot in a smaller tank - it can be done, but I do see a potential conflict between the fire shrimp and the skunk cleaners. They can co-habitate but the fire shrimp tend to be a bit more territorial or aggressive. NOT like the Coral Banded, but there is a distinct difference in the behavior of the fire shrimp and its cousin the skunk cleaner.
If it were me, I'd probably choose one pair of the same specie (ie either 2 fire shrimp or 2 skunk cleaners). They will reproduce and the fry will become fish/coral food.
Black clowns... Ocellaris? They are less aggressive than quite a few other clown species. Should be fine.
Porcelain crabs - be careful.. make sure you get the ones that stay tiny. Some "Porcelain" crabs get large and destructive. There are several species that go by that common name so make sure you know what you are getting.
