Hi rochie, thanks for the photos - I'm building the same model (from the same kit) and I'm struggling with detailed images... I'm trying to make my own decals for an experiment.
As for the props, I just cut the roots of each blade to make them roughly circular in cross-section. But, if you are going to replace them one day, take a note that they rotate outwards (a fairly rare case of symmetry in this regard). That is, you'll need to swap right and left one.
