Hi Derrick,
Thanks for your comments. I will try to respond to each one below. I
agree, the dizzying list of resources can be a bit tiresome trying to
find how to do a simple thing. It's the old trade-off between having
the simplicity versus being able to tweak every aspect of a plot.

Another NCL developer gave me the answer to this one:
There are no italic fonts for the filled fonts, but there are the
stroked fonts complex_italic and triplex_italic - these font
styles are not consistent with Helvetica, but are somewhat
consistent with Times-Roman. You could consider using using bold.
You can see the full font table at:
http://ngwww.ucar.edu/ngdoc/ng/ref/FontTable.html
Click on any one of the fonts to see a full table of that particular
font.
> 2. With the gsn_csm_* templates, can I easily turn the tick marks inward?
The gsn_csm templates were specifically tweaked to turn the tickmarks
outwards (because NCL's default is to turn them in), so it's not as
easy as it should be. The tickmark lengths are set by indicating the
full length of the tick mark, and then using the
"tmXXYYYYOutwardLengthf" resource to indicate which part of that full
length should point outward.
So, by setting the Outward resources to 0, you can force the tick
marks to point inward. Try this:
res@tmXBMajorOutwardLengthF = 0.
res@tmXBMinorOutwardLengthF = 0.
res@tmYLMajorOutwardLengthF = 0.
res@tmYLMinorOutwardLengthF = 0.

If you are overlaying contours on a map, the way to do this is via
the map limit resources. For example, if your data is on a grid
that goes from 32S to 32N, and from 78W to 17E, but you want the
actual map area to go from 35S to 35N and 80W to 20E, then
you can set the following map resources:
res@mpLimitMode = "LatLon"
res@mpMinLatF = -35
res@mpMaxLatF = 35
res@mpMinLonF = -80
res@mpMaxLonF = 20
Note that depending on your map projection, you might want to set your
map limits differently. Please see:
http://ngwww.ucar.edu/ngdoc/ng/ref/hlu/obj/MapTransformation.res.html#mpLimitMode
for a full description of the various options.

You're welcome! Let me know if this didn't answer all your questions.
