Quick AE tutorial:
What I did was set Blender to 1024 x 576 aspect 100 x 100. Then used the script to save a .ma file.
In AE, file menu > import > file and choose the .ma file
This loads a folder of tracking points called Solids and now a single composition element with the name of the .ma file.
Double-click the composition element and it should load all the tracking points into the scene. You can use the manipulation controls in the top left - orbit camera tool etc (hotkey is c) - to move the 3D view.
Use the view menu > look at all layers if you get lost with some crazy camera movement. I wish the compositors had turntable view like Blender.
Now you can add other layers so maybe load in an image then drag it down to the composition.
Right-click the added image and make it a 3D layer.
Reset the position to 0 0 0.
If the Blender camera was looking at 0,0,0 you should see the image in view.
I had to scale the image down to about 0.5%.
The image should stay where it is while the camera moves around it.

To attach a composite object to a tracking point, you can simply parent it to one of the tracking shapes, then just reset the composite object position again if you want it to be in the same place.
