While it may be possible to get Mathematica to generate exactly the
displays that you want in each of the particular situations by dint of
some hackery, you will never be able to anticipate ALL such difference
between a human's preference and the computer-generated simplified form.

If you want a particular ordering (etc) of terms for a document, I
suggest you learn how to use the editor (for you, Word's equation
editor, I guess), to move things around, change fonts, etc.

You can try to thwart Mathematica's notions of evaluation,
simplification, display, but it is like teaching a pig to sing.
