One Gerber file per layer. The file doesn't know which layer it is;
you have to either use some naming convention for the files, or supply
a human-readable file giving the designations.

It's just another layer.

Holes are in the Excellon drill file.
Vias consist of holes in the drill file and pads (etc.) in the
Gerber files for the appropriate layers.

Heck if I know.

I don't know. I last tried to use gEDA two or three years ago, and it
wasn't mature enough then, so I bought Eagle. gEDA is reported to be
much better now, but since I already have Eagle I'm not inclined to

Actually Eagle is available for Linux. That was the main reason I
chose it. You still don't get source, though.
I generally won't run kernel code for which I don't have source, but I'm
more willing to run user-space code without source, since I can use
various tools to make sure it can't do things it shouldn't, e.g., a
chroot jail, and a library preload that prevents network access other
than to the local display.
