That black eye: can't tell from the angle if there had been growth that died, or just that there is a black piece of skin over the eye. If there hasn't been any swelling of the eye that at some point rotted off, there are two possibilities. If the eye area is sunken, the eye may have died. If the area is slightly rounder than flush with the rhizome around it, the eye is OK. However, every new growth usually has 3 or more eyes, one on each side and another one or more behind these. So, don't worry about where your next growth is going to come from, as you probably have enough eyes around.

Picture 3 may not be from too much sun, just natural pigmentation. I would ignore it. The last picture does look like there may be some lighter spots. This may be nothing or may be where some sucking insect left a wound for some fungus to enter. Look for bugs just to be on the safe side. Also, the rippling of the leaves in that shot suggests that the leaf had a few starts and stops as it was developing, and this shading could be some leftovers of the starting and stopping operation. In which case it would be of no concern.
