If I were you I'd dump all your laser energy into either the engines or the shields, your pick. Or you could split it between the two. Then while you're flying to and fro to the station to rescue Antan set your turrents to defensive fire mode. Once you dock the gunning is all you. Yoy really don't need to destroy each target, just make sure they abort their attack run. Good luck.
