Looks like a job more suited for BASH. And for password use Public Keys and ssh-agent.

#!/bin/bash

script=/var/tmp/run.sh

runScript()
{
  local host=$1
  local file=$2

  scp $file root@$host:$script
  ssh root@$host "bash $script"
  ssh root@$host "rm -f $script"
}

host=192.168.10.32

cat <<%%SCRIPT%%
#!/bin/bash
source /home/venkatas/.cshrc
setenv DISPLAY linux37:0
bsub -q linux64_idc_1g xterm &
%%SCRIPT%% >$script

runScript $host $script
