I'll comment on the second one first. It appears to me that the picture was taken with available light (i.e., no flash) and that the shutter speed was too slow to be handheld. Not much you can do about that at this point; no amount of sharpening will take out that much motion blur, I fear.
With respect to the first picture, I might suggest adjusting your scanner properties to a higher ppi and perhaps applying a little sharpening. It's soft, but not really blurry - I believe you can make it look better.
Hope that helps some...
