ssh -A login1 at server1 ssh -A login2 at server2 ./script.sh

This logs you into server1 and then runs "ssh -A login2 at server2 ./script 
sh", which then logs you into server2 and then runs "./script.sh". 
script.sh resides on server2 and has the sftp and chmod commands you 
need.

Run the ssh auth agent (man ssh-add) on the originating machine, and 
then -A will carry authentication forward through the chain. Or set up 
correct auth on all servers beforehand and skip the -As. 

As others wrote, there're more ways to do it; this one is merely the 
most simple-minded and easy to understand.
