I've just pushed up a simple implementation of the above.  The new
function `org-babel-insert-header-arg' bound to C-c C-v j will insert a
header argument and its value using completing read in the minibuffer.

I'm sure the current functionality has room for improvement but it seems
to work well in my initial tests.

Let me know what you think.
