Ok, first thing, the bones in the face need to be renamed with Right in their name, not Left. Also, move the base of the lip bones to the right of center. As for the fan bones not mirroring, that usually means you are not using the correct settings in the mirrorbone plugin. Most of the time it's not using a capital R in Right and a capital L in Left in the plugin dialog.
I also see some of the spine bones are being mirrored, which they shouldn't. Check the spine bones to make sure they are set to 0 on the X and Z axis'. (start and end)
