4. Go through your friends and make lists.
This is the one that can take the most time. You can create different lists of people who have different access to your information. For instance, you might not want your coworkers to be able to see or search for any of your photos. Go to your Friends list from your Timeline and you can see which of your friends is on which list. You can even create new lists and permissions for each list. Lastly, you can view your Timeline as that person by going back to that lock icon in the top right corner, selecting "Who can see my stuff?" and selecting "What do other people see on my Timeline?" From there you can view your info as if you were them.
5. Keep it up.
Lastly make sure you keep an eye on what you share and with whom you share it. The search function is going to make finding infomation much easier on Facebook. Just make sure you want the info you share to be found.
