I think you're getting things all wrong. If your objects are not animated, they shouldn't have any keyframe animation in AE.
IF you have an animated camera, your camera within AE should have keyframe animation.
Your objects center (in your file) are at the world origin (0,0,0) thats why you are seeing them in AE at 0,0,0 also. If you want the external composition tag to be where, lets say, a polygon face is, you'll need to align your object center to that face.
