Sargava, the Lost Colony
Gamemastery Item Cards: Serpent's Skull Deck
And the later adventures have been using lots of creatures from the new Bestiary II, oh and some references to the APG as well.
All of these are optional of course. As a DM I do like Heart of the Jungle and it has rules on additional diseases but would mostly be useful for someone running their own Mwangi game since it has a lot more information in it that SS is not going to cover.
Sargava I think is very nice even despite the fact that the majority of the campaign happens outside of Sargava. Sargava is a major point in the campaign and plays a continuing role.
