Steven is in the cave above Dewford Town (you get there by sailing with Mr. Briney after you save Peeko from Team Aqua/Magma, and you will have to defeat the Gym Leader in Dewford Town [I suggest using Flying Type, since the Gym Leader uses Fighting Types] so you can use Flash, which you get from the hiker as soon as you enter the cave), and Captain Stern is in the Museum in Slateport City. You give him the Goods after you defeat a couple people from Team Aqua/Magma.
