The first thing to do is rip off the lower part of the roof gutter downspouts and put containers under them.

Most furniture is treated with something: varnish, paint, plastic coating, etc, so you might not want to cook over it directly, or burn it indoors where you would be exposed to the fumes. I have a small wood stove, and it can go through a LOT of wood. Just to keep a campfire burning all night (to keep bears and zombies away) takes a lot more wood than most people think.

For the pigeons and crows, put out some cornmeal or oatmeal to attract them, then put up a net that you can trip with a long string. If you've got a gun, you could eat the neighbors' pitbulls that are always running the streets. When you run out of dogs, there are always the neighbors. Eat the nasty ones first and tidy up the gene pool just in case things get better.

If you don't have much food, you'd better have seeds. In addition to planting them, you could probably trade some for food you could eat immediately, like moldy Twinkies.
