Looks like eggs, maybe? I don't know what they are and I'm not sure about cilantro, but black swallow tail butterfly caterpillars LOVE parsley.. before you try to get rid of them I'd put those leaves under a cover and watch it for 7-10 days, see what happens.
As for the white spots, yellow leaves, probably weather damage. Have you had any light frost since this went outside? Cilantro likes cool weather, but can't take frost.
