My copy is older than your's and doesn't have most of the features you're speaking of.
For the development number table, the black is probably the recommended combination, and the grey other possibilities. At least, that's the way it's presented in mine, but mine doesn't have anything in Orange.
No "P" on the developing dial on mine either.
There should be explanations of all that in the text though.
Maybe if you can post some pictures?
