Hmm, not sure about the former, but trying to get first person lightsaber the way RazorAce does it (moving the camera to the eyes I think) would require code changes and the sp code has not been released.
i have a solution for this
use notepad creat a empty text, then rename it writecfg.cfg.
but it not work forever because whenever you reload game or load save game it will come to default
ps: sorry for my bad English, I'm not American
