I doubt that anyone does a boat tail first, it is one of the biggest modifications, both in terms of size, time investment, and looking... weird...
The largest possible modification is driving technique, but for aerodynamic improvements, I think that it would be difficult to beat a boat tail.
You listed areas of drag, but front and back wheel skirts and a belly pan might equal the improvement of a boat tail. With modifications from bumper-to-bumper, you might get attached airflow, but your vehicle will still have a giant wake.
Basjoos has all of the above modifications and plenty more.
