Usually iphone or even mac joins a previously known network automatically. I have not seen my mac switch automatically from one to another unless it drops the weak one due to signal strength.
Yes, you can extend your wifi through the house making it just one network. Not sure what routers etc you are using but for Apple's airport networks, you can take look at this http://manuals.info.apple.com/en_US/Apple_AirPort_Networks_Early2009.pdf

That's what I'm hoping the iPhone would do. When the signal strength of one known network drops and another rises (e.g. going from upstairs to downstairs), I wish it would switch to the stronger one automatically. Does it cling to the original network as long as there's some shred of a signal?

Yes. The iPhone's WiFi is not as sophisticated as the Airport card in your Mac. You should extend your network rather than have two networks.

Too bad. I find that the iPhone does the same thing with 3G. It would rather struggle with one bar of 3G signal rather than switch to a better performing Edge signal.
