Hey Charmaine, if you paid for these items then all you need to do is go into the app and in the settings (bottom left) and find and click the button for 'restore purchases' and the lives and boosters will return to your game.
As for finding your facebook friends. I have the option to type their name in on my PC game, do you have that option?
