They will not eat or otherwise harm your leaves. Worst case scenario, they might poop on the leaves...leaving a small red spot here and there. Again, if there's only one or two, this isn't anything to worry about. You should be sure to leave a small dish of water in there for them, or they'll get dehydrated and die.

As for earthworms in your soil, there's nothing wrong with that either. Earthworms will burrow and move around all throughout the soil, making for natural aeration, and they will not harm your roots. Also, earthworms expel waste through their skin, known as 'castings', and this is very good for the plants, as it contains plenty of organic goodies. If you don't want a bunch of squigglies roaming around your soil, adding pre-packaged earthworm castings is a fine alternative.
