With LR, you are looking at more of a refugium than a wet/dry filter (but its not really a refugium since you won't have a sand bed and plants). You could put the LR in the first chamber where the water enters and have bioballs in the trickle chamber and get the effects of both. With LR you will need light in order for the coraline algae to grow. You may want to add another baffle or two before the return see: http://www.melevsreef.com/sump.html
Hope this helps.
