I just want to set the value of some complex points via dragging locators
around. Then I want to set the corresponding positions of 3D points, with z
values adjustable via sliders.

Do I have do everything from within a single DynamicModule to do this? I'd
also like to preserve their values between sessions. Is DynamicModule the
recommended way to do this also?

The Dynamic[p] on the outside doesn't get updated via the Dynamic[p] within
DynamicModule. 

Dynamic[p]

DynamicModule[
 {p = {0.5, 0.5}},
 {
  Graphics[
   Locator[Dynamic[p]],
   PlotRange -> 2
   ],
  Dynamic[p]
  }
 ]
