The answer is no.
W/D's etc do not remove NO3/PO4 etc, plants do and are quite effective at
it. W/D's are good at converting NH4 to NO3 and gas exchange. Lave rock
works fine for most situations. Unless you need max filtering from a minimal
sized wet/dry tower(eg a built in on the back of the tank wet/dry filter),
then lava is fine.
> Would it affect the filtering properties if it were kept in the dark?
No. It's do better for the bacteria but if you added light, algae will grow

No. No surface skimming etc, more cleaning.
> Would darkness have any effect on them also?
> Would a combination of both wet/dry and sponge filters be beneficial?
Not really. If you needed more, just have a bigger bio tower. You can also
add the sponge into the sump somewhere.
