If you bring up the Background Map Control (click on the 
Blue name in the legend or click on the Display Controls
tab in the Dashboard), you will see where you can set the
color and width for the map.  You can also set the positioning
in the box under the Display tab of the Map control.

Projections seams are problematic.  There's no way to indicate that
the next value after 355.8 should be 1.4.  You might try turning
on Fast Rendering under the Edit->Properties menu of the display
control for your plot to see if that makes any difference.  That
avoids the code that adjusts for projection seams, but might
introduce other problems since you are not in the native projection.
Going from -180 to 180 in the file would solve the problem over 
Africa, but would create problems over the date line (although
presumably canopy heights are not a big factor there. ;-)).
