Jack Frost vs the Garden

We've got a freeze warning for Fri, Sat, and Sun nights currently. I'm not sure it will actually get down to 32 or below any of these nights, but I suppose I must be prepared, for the sake of the garden.

I know the garlic (coming up nicely) and parsley will be just fine. I think we're going to cover the cherry tomato plant, as it still has a couple dozen unripe tomatoes on it. I'll pick any that are even remotely turning red, but then cover and hope for the best. I need to look at the other tomato plants more closely, but I'm leaning towards just picking all the tomatoes and pulling up the plants. Probably the same for the bell pepper and hot pepper plants, though all are still producing well - especially the banana peppers and jalepenos. I picked a good dozen today, off 2 plants. I may just try to cover them, after picking all the good size peppers.

The only other things still in the garden are the basil (almost dead), cilantro (self-sprouting like crazy), and the late potatoes. I know that spring planted potatoes are put in well before the last frost, so can they take a frost?? I've never planted potatoes before, so this is a total experiment...
