About the candle/lighthouse and its possible connection the "Shovel that Good Snow" - I would have to re-read the whole book to find the exact place where he said something about shoveling good snow. He mentions shoveling snow a lot. He uses it mainly to describe his job, he says that it's like shoveling snow - someone has to do it.
If it is a lighthouse and not a candle, there is one connection I can make, Gotanda drove his Maserati (The one with the 'Curse of the Maserati) into the ocean. You find lighthouses by the ocean.
WE ARE CONNECTED - That is what the main character realized. He realized that he, Mei, Kiki, Yuki, Gotanda, The Organization, The Sheepman, Ame, Dick North, and pretty much everyone else was connected. He later made a diagram.
