No it doesn't.

Use the "text" instruction to add that. Sorry, the scalebar is in inches
and text is in percent of map frame, so it takes a little adjusting to
get the placement right (beyond 0-100% is ok for out-of-frame).

scalebar
  where 2.95 15.15
  length 10000
  segment 5
  numbers 5
  background n
  end
text 21.5% 2.6% Meters
  ref bottom center
  end


same issue for the colortable fp legend.

no idea.

Yes.

An alternative for journal-quality output is to use GMT for the
plotting. GRASS "does" cartography, but it isn't specifically a
cartography package. GMT is.

there are some GMT export scripts on the wiki add-ons page, and other
help on the wiki and mailing list archives too:
