The program you are already using is said to convert grib2 to netcdf:
http://www.nws.noaa.gov/mdl/NDFD_GRIB2Decoder/
and there are several modules providing a netcdf interface for numpy.  I 
like this one:
http://code.google.com/p/netcdf4-python/
and it is included in Enthought Python Distribution.

For GRIB to numpy, googling turned up http://code.google.com/p/pygrib2/
as well as PyNIO.  My guess is that this (pygrib2) will be exactly what 
you need.  It is by Jeffrey Whitaker, the author of the above-mentioned 
netcdf4 interface as well as of basemap.

Well, I recommend switching to linux anyway, but that is another story.
