I cut the back of my ash pan off so that dumping it makes less of a dust plume. It also makes more room for poking in under the grates. I only have the ash pan installed when I shake the grates and remove ash. This is so that heat radiating down thru the grates can heat the floor of the fire box, which becomes added heat transfer area.
As long as you don't let ash pile up under the grates you shouldn't have a problem with the grates warping. I've never warped a grate in three years. BUT I have broken the nub that the handle slides on to by shaking it too hard.
