Amitabh congratulations!  I admire your persistence.

Do you use matlab?  If so take a look at:
http://mitgcm.org/pelican/online_documents/node95.html

Also in the documentation, chapter 3, for example:
http://mitgcm.org/pelican/online_documents/node109.html#SECTION004102100000000000000
there's a discussion of numerical stability criteria.

Another approach is to use parameters from previous
experiments that are similar to yours, for example:
http://mitgcm.org/cgi-bin/viewcvs.cgi/MITgcm/verification/global1x1_tot/input/
and then fine tune through trial and error.
