You can find out specific levels for the commands that you want by
show privilege command [command]
Most things are level 15 or level 1. I believe
show privilege all
shows everything with it's correspinding level and
show privilege level [#]
would show just commands at that level.
You can assign different commands to each level and it processes via heirarchy - if you are a level 10, you can execute any command assigned to your level and lower.
