(Answering the easy question first)

Currently the arrow is a GtkArrow with GTK_SHADOW_IN set for the shadow
type.  You can theme this currently like:


style "sort-indicator" {
      bg[NORMAL]="#FF0000"
}

widget_class "*.GtkTreeView.GtkButton.GtkHBox.GtkArrow" style "sort-indicator"


In theory you can also have a theme engine handle the drawing.  This is
a little ugly, and perhaps we should just go to drawing the arrow
ourselves and pass in a detail, but it works.
