Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

My members of the wheel group can su however, I would like for an additional user to have the ability to su but not be part of the wheel group. New to Linux so please forgive me. Below is my /etc/pam.d/su configuration file. If it's easier I can create a second group and add this person to the group. I just don't know if I need to add a comma or a semiloclon to seperate indivdidual groups in the su configuration file.
auth sufficient pam_rootok.so
# Uncomment the following line to implicitly trust users in the "wheel" group.
auth sufficient pam_wheel.so trust use_uid
# Uncomment the following line to require a user to be in the "wheel" group.
auth required pam_wheel.so use_uid
auth include system-auth
account sufficient pam_succeed_if.so uid = 0 use_uid quiet
account include system-auth
session include system-auth
session optional pam_xauth.so
A million thanks,

This does not have to involve PAM (as far as I can see) but simply a well-tuned user account. Make the new user, add him/her to all the required groups except wheel...better yet, look into sudo instead...
If I have about 25 to 30 existing users, it seems like allot of sudo configuring as oppose to creating a group and adding the user to the group along with the group to su configuration file. Am I overthinking sudo?
