An insect ate holes in the leaves.

Look underneath the leaves. If you see the creature (or creatures) that did it, get rid of them. If you don't see anything, hopefully they're gone -- perhaps a helpful bird ate them.

Looks like slug or flea beetle damage to me. I've been fighting flea beetles all summer and some of my leaves look exactly like that.

If you mean 'is it big enough to bear fruit before frost', maybe, depending on days to harvest.

I would repot it. Days of harvest depends on where you live. I'm in 8b. Our first frost is usually Nov.9-15.
