how do you reflect light off of one object onto another?

Radiosity is the term for reflected light. The option(s) can be found under Global Lighting in the Lights panel.

It is very computationally intensive, though, and sometimes (to me, very regularly) the subtlety of radiosity isn't worth the added rendering time. I've used "fakiosity" fairly successfully, which is just placing additional point/area/linear lights set to very low intensity in appropriate locations.

If you're going to use radiosity, I'd recommend reading the material in the reference manual about the methodology and the options you've got. Very small changes in the settings can significantly change your render times, and as I mentioned, sometimes it's just not worth it.

Radiosity for indirect diffuse illumination. Caustics for indirect reflected or refracted illumination. Caustics are also found in the Global Illumination settings, and they will also increase your render times by quite a bit.
