To fix the problem with arrows stuck in the character, make sure the game is running as stated above, from disc. Back out to the Dashboard and reload the game by pressing "A". Continue holding "A" until the Bethesda logo shows on the screen (Yes, its the good old texture cache reset from Oblivion and it still works with Skyrim
). A friend of mine had the same issue and he'd started a new character to get rid of it, sadly. If the upcoming patch doesn't fix this also, now you at least have a workaround for the issue.
