Help Installing Nest Thermostat on Millivolt System Using 24v Transformer

I just purchased a new Nest thermostat. My old thermostat gets power from an ancient millivolt system (thermopile on top of pilot light generates 0.7VDC). This is incompatible with the Nest, since the Nest requires standard 24VAC. Nest support told me they've heard some customers have had success using 24v step-down transformer. After lots of research, I think the wiring is supposed to go something like this: W from furnace (common, -0.7VDC ?) --> W on T-Stat 24 VAC power from transformer (+/- ?) --> C on T-Stat R from furnace (+0.7VDC ?) --> RH on T-Stat 24VAC power from transformer (+/- ?) --> RH on T-Stat As you can see, I'm still a bit fuzzy on the details. Questions are below the fold! [more inside]

I've lost my light installing mojo.

We decided to replace an ugly old chandelier today. After turning off the breaker and taking off the chandelier, I noticed there are black, red, white and green wires. The house is circa 1968. From what I can tell there used to be a fan/light. So I hooked up our flourescent dome by matching the wire colors and capping the red wire. Unfortunately, it didn't work. [more inside]
