Actually, that pretty much covers it for my needs. I would have the ability to 'sudo su' and do elevated tasks, but there might be cases for others where the logged in user would not be able to sudo to root, so they would have to sudo the command itself (as opposed to sudo to root and then running the commands).
I love to have this work for me, but there is a larger segment of potential configurations that should be addressed so the most correct resolution is put into place.
To specifically answer your question...
ssh <user>@<server.host>
sudo su
<passwd>
<command1>
<command2>
<etc>
