For a DEM, be sure to try NVIZ.

I don't think that's needed.

v.to.rast only works on features with cats/attributes.
Perhaps the labeling isn't right. Maybe 'v.category option=add'?
See the "notes" section of the help page:

why not just to d.vect. The version in 5.7 lets you set icon= type,
size/color, and border color and is very nice.

Try d.out.png.

ps.map makes excellent output for a printed hardcopy, but for a
presentation I think using a sscreenshot of a display monitor works best
(or PNG driver). Try to get the monitor the size of the final image so
it doesn't get streched & uglified.

If you must use a PostScript plot in a presentation, the best conversion
I've found is to load it in the GIMP at ~ 144 dpi with strong anti-
aliasing on both the graphics and the text. Otherwise it comes out
grainy.
