Having read this belatedly..
The only thing I'll point out, having worked in newspapers (on the advertising side) is that you omitted the poor sad copy-editor, versus the "Editor", versus the "Editorial" folks; I've seen them get confused with each other.
The deadlines can be a bit looser if the paper in question does have their own presses, but only sort of.
Also, no one ever really gets to yell "Stop the presses".
