If you're told do something for "Each land that..." / "Each board that..." / "Each Spirit which...", do you check which lands/boards/Spirits to affect at the beginning and then not change that list (like figuring out which lands Ravage)?

Yes. Selectors like "On each board with Cities" or "In each land with Explorers" or "Each Spirit with 3 or more Dahan among its lands" select the set of affected items before resolving any of them.
