And you might add a second bit to the line suggested below

    %wheel     ALL = (ALL) ALL, ! /usr/bin/su -

This should prevent someone from explicitly executing "sudo su -"

Of course, someone with sudo rights to ALL like this can easily get 
around not being able to "sudo su -" in a dozen ways (like "sudo 
/bin/ksh", etc.).

But the error message that comes back acts as a gentle reminder to be a 
good citizen and not do things like that.

I recently found this well-written overview of how a user should think 
about sudo (and not resent having to type "sudo" in front of everything)
