As Even suggests you should read the tutorial first, most questions will be answered there.
As for Band extraction, you need to look at the metadata, which you can inspect with gdalinfo you should look for metadata like NETCDF_DIM_time_DEF NETCDF_DIM_time_VALUES and band metadata like NETCDF_DIM_time=1 If you want more fine-grained control on band selection based on a particular dimension (in this case time), then perhaps you should look into software that specializes in netcdf format like nco or cdo.
