Hi Ram,

For WRF, which only uses netCDF-3, it is sufficient to install the latest 
netcdf.tar.gz, which will be version 4.1.1, from

  ftp://ftp.unidata.ucar.edu/pub/netcdf/netcdf.tar.gz

and build it from source using the default configure options and 
--disable-dap.

I think the WRF users guide answers your other questions, where it says:

 http://www.mmm.ucar.edu/wrf/users/docs/user_guide_V3/users_guide_chap2.htm

  If netCDF-4 is used, be sure that it is installed without activating
  the new capabilities (such as parallel I/O based on HDF5). The WRF
  modeling system currently only uses its classic data model supported
  in netCDF-4.

  If you are going to be running distributed memory WRF jobs, you need
  a version of MPI. You can pick up a version of mpich, but you might
  want your system group to install the code. A working installation
  of MPI is required prior to a build of WRF using distributed
  memory. Either MPI-1 or MPI-2 are acceptable.  Do you already have
  an MPI lying around? Try

         which mpif90
         which mpicc
         which mpirun

  If these are all defined executables in your path, you are probably
  OK. Make sure your paths are set up to point to the MPI lib,
  include, and bin directories.  As with the netCDF libraries, you
  must build MPI consistently with the WRF source code.
