You are right that \shape is affecting only the first piece of the
slur.  All you need to do to adjust the second bit is to add a list of
offsets for that part.  Something like this:

\shape #'(
                ((0 . 0.5) (0 . 0.5) (0 . 0.5) (0 . 5)) ; first part
                ((0 . 0) (0 . 0) (0 . 0) (0 . -1)) ; second part
               ) PhrasingSlur

Same reason I switched from Finale!  By the way, one suggestion that
will make using LilyPond even more attractive: instead of repeating
\change Staff = "upper" you could do

up = \change Staff = "upper"

so then you only need to write

\up
