As you are using the pam_sge-qrsh-setup.so you will need to set
rsh_daemon to point to a rshd-wrapper which you should find in
$SGE_ROOT/util/resources/wrappers eg if $SGE_ROOT is /opt/sge

rsh_command /usr/bin/ssh -X
rsh_daemon /opt/sge/util/resources/wrappers/rshd-wrapper

No it should be fine without a restart

That looks fine, assuming sensible default resource requests, although
obviously I don't know the details of the wrapper or application.
