use a 12mm ratcheting box-end wrench to make access easier - hard to get to with sockets. Thread the new ones in by hand - last thing you want to do is cross-thread the holes. Some people put a little oil on the threads, some don't - I think the torque ratings for the plugs are for dry threads.
If there's a lot of carbon in the holes, you'll probably want to ream out the excess carbon before putting in new plugs. And don't lose the nuts holding the electrical wires on the plugs - they're a bear to relocate once they fall off into the engine bay.
