most newer modules have lsboxhook-bang. u'll have to use that to load the module into a box. one important thing is that u have to load that module before it is being hooked to a box, that means if you're loading your boxes in step.rc (when litestep starts) then u have to load the module before loading lsbox.
basically u got it right, but remember, when a module is loaded into a box the 0,0 coordinates are in the top left corner of the box not in the corner of the screen ;)
