In your post, you say "This morning I looked through my privacy settings and I can no longer seem to find individuals who I had set to limited profile access."
As part of the privacy changes, Facebook automatically created a new friend list for each user called "Limited Profile" and put all of the users who you set to limited profile access in this new friend list. Just go to the friends page and you should see the new friend list on the right: http://www.facebook.com/friends/.
