Humm, for the blink, if I remember well, you have to add a useless part to the head's bone(like a part smaller than the head that you will hide inside the head) and make sure that, in the HRC, the first part of the head's bone is the useless part. That way the invisible part will blink but it will never be noticed by anyone. Beside if don't texture the useless part it won't blink.
Sorry if what I said is unclear but it's hard to explain on a forum.
