you can use ssh to directly run commands on remote server like this

Code:
ssh root@remote_host "/tmp/script.sh"

This will prompt you for password, unless you have copied your local user's public key to the authorized_keys file on the home of user .ssh's directory. This will allow for password less authentication.

try using here document in shell script to achieve your requirement

Code:
ssh srom@$a << EOF
password
/usr/local/bin/sudo su -
Scripts_you_to_run
exit
EOF

sudo does not prompt you for password? you can even skip copying the script, and running su just to run another shell...

sh has -s option to read commands from stdin. example:

Code:
[mute@geek ~]$ cat local-script
echo Hello World >/home/mute/test.txt
[mute@geek ~]$ ssh mute@localhost sudo /bin/bash -s < local-script
mute@localhost's password:
[mute@geek ~]$ cat test.txt
Hello World
