Dave,
Sylvia Murphy has a whole page dedicated on how to create
labelbars using the gsn_csm templates. Please go to:
http://www.cgd.ucar.edu/csm/support/CSM_Graphics/labelbar.shtml
and in particular, look at example 3 which shows how to move the
labelbar away from the plot (using the "pmLabelBarOrthogonalPosF"
resource).

You can use "+" operator, which serves as a string concatenator when
used with strings:
res@gsnCenterString = "Plot " + n
NCL will convert the value of "n" to a string, and then concatenate it
to the string "Plot ".
If you need to format a variable when writing it to a string,
you can use the "sprinti" and "sprintf" functions to format
integers and floats respectively. For more information, see
their web pages at:
http://ngwww.ucar.edu/ngdoc/ng/ref/ncl/functions/sprinti.html
http://ngwww.ucar.edu/ngdoc/ng/ref/ncl/functions/sprintf.html
