Leigh,

I have modified the code to attach the following information the "inventory" structure in the degrib library to each band. I think this covers several of your items. But I'm not clear on what you want for "The data" and whether these cover "type" and "product name". The high level api does not expose the raw product code octet sequence, but I should be able to drill down and get it if it is needed. 

    GRIB_UNIT=[gpm]
    GRIB_COMMENT=Geopotential height [gpm]
    GRIB_ELEMENT=HGT
    GRIB_SHORT_NAME=1000-ISBL
    GRIB_REF_TIME=  1118707200 sec UTC
    GRIB_VALID_TIME=  1118710800 sec UTC
    GRIB_FORECAST_SECONDS=3600 sec
