Okay, so I have <user> added to group sudo in /etc/group.
tape:x:26:
sudo:x:27:bmike1
audio:x:29:pulse

I have the lines:

# Allow members of group sudo to execute any command
#sudo   ALL=(ALL:ALL) ALL
%sudo ALL=(ALL)  NOPASSWD:  ALL

in /etc/sudoers and as a result sudo no longer requires a password for my user. I then figured I would test this so I commented out my user in /etc/group (sudo:x:27:#<user>) and then opened a new terminal and typed in  'sudo visudo' fully expecting it to ask for a password but no password was requested. So what's up?

Either create a new group or use an exiting group that is not being used.  and then add the group to the sido script.  so for a new group:

1.  Add a new group to /etc/group with the following command:

    groupadd groupname (where groupname is a single word)

2.  Open the /etc/group file and add your username to your new group as discussed before.

3.  Open the sudo script file with visudo and add the groupname following stanza to the file:

%groupname ALL=(ALL) NOPASSWD:  ALL 

This is basically the same thing.  If you are the only user or admin on your system than this is overkill and you could just use the %sudo group stanza as discussed before.  However if you are planning or have serveral administrators that will have different permissions than it would be best to re-think not using passwords.
