is set by pdftex, so don't ever change this one!

or cropbox=trimbox

the cropbox sets the output size on the screen (what is shown); so if
you set it to the trimbox values, the outer bleed|media box part is no
longer shown on screen

yes (as I understand it; I'm no printer)

I would suggest, that you don't use this for you current project.
There is no need to use low level commands here.

There is (at user level, but work in progress)

% (currently only a copy of the mediabox values)
\setupinteractionscreen
  [trimbox={[0 0 595.2756 841.8898]},% values are ignored
   cropbox={[0 0 595.2756 841.8898]},
  ]

and

% low level
\doPDFpageattribute{/TrimBox [0 0 595.2756 841.8898]}
\doPDFpageattribute{/BleedBox [0 0 595.2756 841.8898]}
...

The values are from one of my test files, so you have to calculate them
for your example. The first two values represent the lower left corner
(in pt), the last two values represent the upper right corner of the
box. Reference point is the lower left corner of the media box.
Bleedbox=Mediabox, Trimbox[ 0.125" 0.125" 6.125" 9.125"] (but in pt).

Good luck and success for your book.
