I just found one remaining memory leak among the memory leaks you mention above. Fixed in trunk in r15255.
I suppose from the line numbers of your Valgrind report that you're using GDAL <= 1.5.2. The GRIB driver seems to have undergone major changes in SVN trunk (moved from spike to trunk in r13877, so most of the issues raised seem to have been fixed in GDAL 1.6.0dev)
