That's basically the way it goes. just place a1, a2, and a3 randomly on the front area of the ship, b1, b2, and b3 on the front starboard and so on... If you want this model to be used in SFC3, make sure you place the damage points where you want damage textures to show up and they're intersecting the skin of the model. If they're too deep in the model, the damage textures won't show up in SFC3.
