Unfortunately, it will be difficult to customize Scribble's Latex-based
output without understanding Latex. Maybe we can get you just far
enough with this customization...

To answer your original question: Yes, you can use
`make-latex-defaults` that way. Instead of using `part` directly, it's
easiest to use `title`, so that you don't have to fill in all the
fields of `part`.

Another piece of the puzzle is that `\myname`, etc., need to appear in
the Latex output before the title. A Scribble paragraph with the
'pretitle style property will do that.

The enclosed "latex-default-ex.scrbl" illustrates.

Normally, I'd expect `make-text-addition` to work in the way that
Matthias suggested, which would mean this simplification of

 @(define tma-style
      (make-tex-addition #"\\usepackage{cancel}\\usepackage{tma}"))))

But `make-tex-addition` causes "tma.sty" to be pulled in later, and
apparently that conflicts with one of the packages that Scribble uses.
Such is life with Latex, and the simplification doesn't work.
