I don't know much about pond but I'm sure that you'll have to deal with lots of critters.
About leech, they won't kill your fish but they will feed on your fish, or any other animals including you. So it's best to get rid of them.
About the lice, you might be having fish lice. They look pretty much the same but they do live in the water. These are pretty dangerous to fish as they can cause some serious infection. Get rid of these and monitor your fish carefully. Any sight of stress/flashing should be treated with fish lice treatment.
