Caustics from the floor will make little difference in this scene, because
they will be overpowered by the direct light. Even the light contribution
from diffuse interaction (radiosity) will probably be brighter than what
comes from the photons. If you want to, try rendering it both ways and then
do a difference on the two images to see how much light the photons
contribute. Personally, I'd find that very interesting.
The reflective caustics from the cylinder, unfortunately, will always be
very dim. The shape of the cylinder disperses the light, so that it is much
dimmer and is drowned out by the direct light. That kind of reflective
caustic is generally only visible if it reflects into a shadow, and even
then it is dim because the light energy is spread out over a large area.
