Show Custom Profile Fields in Staff Directory

[Computer Candy]

I am helping with a school PTO (i.e. PTA) website. I created custom profile fields to show what committee some members are on. I would like to have those fields show in the Staff directory. Can anyone point me to some kind of 'Staff Directory Templates for Dummies' (or anything in the ballpark) on how I might be able to easily add them? Thank you.
