David's right about the player.prf being all that's required to restore your game from the "progress" point-of-view (in fact the player_backup.prf & player_backup2.prf aren't necessary as they are immediately recreated from the player.prf when the game starts, but all three at level 0 would need to be deleted before the backup player.prf was copied in.). However, the player.prf does not hold any info about your FL directly; it has associated with it a "suid" (System User ID?) number that is used to pull down the assocaited FL from the servers when the game starts. This number seems to be device specific because a fresh install keeps the same number active (it's how the server recognises that you've played the game before and asks if you'd like to continue where you left off (keep friends) or start anew (wipe friends!)). Think of the Friends_List.xml in the Social folder as a cache of your current friends...this file is constantly being updated by the server which holds you master FL. If the FL gets wiped on the servers, copying a backup of the Friends_List.xml back into the Social folder isn't going to work as it will immediately be over-written by the updated server version (no friends!)...the data moves only one-way, from server to game device.
