The Adventure Pack scenarios tend to be relocatable in terms of time and place (and most offer suggestions for this), but as they stand:
Blight Night is set on the southern edge of Davokar and is something of an introductory adventure, so I'd say pre Wrath of the Warden. I actually took the suggested option of moving the location to the Titans and ran it straight after The Promised Land, since it was a useful way of introducing the PCs to the situation in Ambria.
Adventure Pack 4 has two scenarios. Call of the Dark is set in and around Alberetor. It doesn't really need anything from Throne of Thorns to have happened, since it deals with the transition of the old Alberetorian nobility into Ambrians, but its location, and the fact that its an Expert-Veteran adventure would suggest setting it immediately prior, or early into The Haunted Waste. The second scenario works best if Mother of Darkness has happened, but thats not a given. Assuming you're going with that though, again, early into The Haunted Waste.
Other opinions may differ.
