As for people that have a problem with Rey "all of a sudden knowing how to fight with a light saber", the first thing I noticed when she was fighting Ren was that she clearly had no idea how to use the thing. I thought they did a good job of conveying that she was new to it with the way she was thrusting at him. It looked very awkward to me, which, I think, was intentional.
Also let's face it, the battle didn't end because Rey "won". The earth split apart so that ended that right then and there. Yeah, she had him down but we will never know if she truly would have won that battle. Technically it wasn't over yet.
