3 fine additions to your collection, I think you'll be happy. Dark of the moon is one of my favorite 3d movies, I'd watch it all the time. Now I just seem to watch Avengers over and over and over again. lol (though I've watched all 3 of those multiple times)
I know some of RE:R's soundtrack was recycled from RE:A, not sure which bits.
Fritz! Fritz, get up for God's sake! Get up! They've killed Fritz! They've killed Fritz! Those lousy stinking yellow fairies! Those horrible atrocity-filled vermin! Those despicable animal warmongers!
