Hi Steve,
You can look at the regridding page of the examples: http://www.ncl.ucar.edu/Applications/regrid.shtml
Especially take a look at the regridding decision tree.

Another more visual solution is to use the technique of drawing a plot
of the data in its native projection, then using the ndctodata
function to get the lat/lon positions of the grid points. There is an
example of this technique on the "native grid projection" page: http://www.ncl.ucar.edu/Applications/native.shtml
. See the last example: native_5.ncl.
