I got all of them. And like in most games I do lots of things the first time by accident and when I try to do them again, I find it very difficult (like I actually crossed the swamp in FFVII on foot without facing the midgar zolom on my first play though, which i didnt finish). I found getting the the mythril sword of Beatris the hardest because of the time limit of the battle. I stole it the first time without any trouble, but after that one time, it all ways takes me at least two attempts at the battle to get it.
