Little syncing question

I've been having problems with my phone lagging and freezing, so I tried the factory reset. After messing with the dang thing for about 1/2 an hour, I finally got it to reboot. I'm in the process of adding all the apps I lost, including facebook. The facebook app is working fine, but I didn't have any of my facebook "friends" in my contacts list like I had before I reset the phone. I tried adding facebook in my accounts, and that helped, but none of their profile pics are coming up and now I have every email address I have ever sent from my gmail account listed as a contact! How to I get it so I can't see the email accounts and all my facebook buddies have their pictures up and everything is good!?
