I'm doing a tiny house sort of project and plan to have a sink and propane camp stove inset into a wooden countertop. What sort of wood should I use, and how should I finish it to reduce the risk of fire, staining, water damage, etc?

Wood works great for countertops if you are willing to live with visible wear or even welcome the scars of daily use as part of the charme of a lived-in environment.
You didn't mention which part of the world you're living in, so it's a bit difficult to recommend one wood over another - in general I'd go for something local that holds up well to rot and warp. In a rural environment, you might ask a farmer what they're using for (wooden) fenceposts. To name two less frequently mentioned choices that should be easily available in North America: Black Locust (Robinia pseudoacacia) is very resistant to decay, and would hold up well in a wet environment. The same would be true for Osage Orange (Maclura pomifira), though the latter tends to come in smaller and gnarlier sizes. Depending on local availability, they might both be worth looking into.
About the woods mentioned by other replies: Maple in particular would be a wood I'd rather not use in that context, since it is not exactly known to hold up well to rot (and its bright colour and smooth grain would spell out any scruffs in all their glorious details).
You have three sources of damage to your wooden countertops:
From personal experience, you will want to keep both stovetop and sink installed in a way that keeps liquids from creeping into or under edges and heat sources at enough of a distance. I would aim for a flat, embedded installation, and make sure to use a flexible sealant for caulking. Depending on the wood used, the endgrain around the cutout could be primed with epoxy. This would have to be done prior to oiling the countertop.
Even more effective in the long run would be to reduce the amount of seams that need to be covered by choosing a modular sink that covers the belly-to-backsplash disaster zone with its own waterproof material without exposing wood nearby.
There are many examples to be found across the web - just don't fall for the shiny interior-decorating-magazine pictures but imagine the setup after a decade of day-to-day use.
Distance of burner: If you already settled on a burner - experiment in a safe setup which distance would be safe: Use a large pot to find out how far the flames will reach around, and make sure that radiated heat will remain low enough to avoid charring. If you have to install some kind of heat shield, keep in mind that the shield itself may get hot and cause the wood behind it to char unless properly insulated.
