Am i taking the right approach

Having done a lot of this, I would:

  1. Set up an ssh-key, to log in automatically without Expect - as a non-root user.
  2. Write one Expect script for each of the (few?) commands that are interactive.
  3. Write one straightforward wrapper to tie it all together.
  4. Enable the non-root user to run the wrapper with sudo.

Something like this: 

ssh admin@host "sudo /path/to/wrapper.pl"

Where the wrapper might: 

...
die("...") if system("/path/to/cmd1.sh")!=0;
die("...") if system("/path/to/interactive-cmd-exp.pl")!=0;
...
