My question is, where in this lash-up do I connect the shield of the RG-400 to the ground radial system - at the SO-239 where the feedline comes into the box (before the chokes) , or at the end of the second choke that connects to the inverted L, or ?

On the antenna side of the chokes. Think of it this way, Pete -- the radials are part of the antenna, the chokes isolate the feedline from the antenna, prevents the feedline from becoming a radial.
