Even the smallest amount of copper will kill inverts and corals outright. The liverock you have in the tank now probably has an enormous amount of dead or dying inverts/bristleworms etc. watch water quality closely as the liverock will now have no life on it (no worms inside to burrow means the liverock can now become clogged and not filter as well over time).
As for the lip injuries. It sounds like a bacterial infection, however i dont recomend you start a new treatment for this until you have finished the treatment for the ich. When (and only when) you are satisfied that the ich is gone) should you do a large water change and then start treatment once more.
You could try dipping the fish in a bacterial dip. this could work but sadly the chances of catching them whilst the rock is in the system will be difficult.
