Velociraptor: UV Mapping My Anger, the Trilogy

Sooooo.... the pelting plugin helped a lot. And now I'm stuck on how to duplicate my UV's properly for the other side of my legs and arms. I tryed going back and just mapping it out with the plugin again but it likes to erase all my UV's when I do that. Needless to say, I have a headache again and need to take a break.
