Paizo ain't wizards, they give you lots of information about how to run a game, even down to the general amount of money they should have or the amount of events they should fight in a day.

The experience can be useful for a type of campaign you haven't run before i suppose, I'm doing sevenfold conspiracy and it has lots advice on running an investigatory whodunit. Although i wouldn't look to the paths for hard balancing advice, the wrath game I'm in is exceptionally easy (until it suddenly isn't) and the game I'm running is pretty easy too (but it's not based around combat).
