Seriously, though:
On the first one, I'd leave her as is until you get to a point when you think the scales are unsafe. Then I'd take the whole thing apart, do the cleaning, and rescale her. That's because I'd rather do the cleaning when she's out of her scales and get it all done at once, but I'd want to save the original scales as long as possible.
On the second one... I'd just leave her as is. I think it would take a regrind to address the uneven wear, and since it's just cosmetic, I don't think it's worth it.
