Is there any significance to the radius of the circle which circumscribes the Golden Rectangle?

Not that I can think of. The golden rectangle can be any size, so this radius can be anything.

Allow me to reiterate: is there a nontrivial significance for the angle whose tangent corresponds to phi, the golden ratio?
