What is the recommended way to upgrade an installed portable app? Delete the whole highest-level program folder first? Delete only the program's apps folder? Delete nothing and overwrite? I'm just getting started with portable apps; what are the factors and choices for upgrading when a new version comes down the pike?
Copy the new version right over the old.

All the apps released by PortableApps.com support what is refered to as in-place upgrades. This means you can install a new version right on top of the old one. None of your data will be lost. This applies to all the apps and to the platform itself.
Sometimes, the impossible can become possible, if you're awesome!
