Hi Dave

Grass is really powerfull and has functions that sometimes
you can find only in "some thousands $ commercial software".
But to really use this power may need to have some skill
in coordinate system and map projection use.

Yes but only in WGS84 system. I think is always better to generate
text files to import.

Yes, using a paint program outside grass (e.g. The Gimp)

Yes comfortably by The Gimp, you can simply generate a bitmap file with grass

Maybe, but sometime is more simple give some prompt command.
