OK, I just checked this particular scene in the original version of Revenge of the Sith (don't ask me how), and I'm now positive that Padme says "Hayden- help me, please..." in her dream. If anyone else can come up with a different word she was trying to say, go ahead- but it seemed very clear to me.
I don't think that Luke shouts "Carrie" at the end of SW, however. It's very indistinct and could really be anything.
