No. Thor and Hulk don't need to finish their arcs. Past their primary development, any changes in their characters are not part of something with an ending.

And I never said Tony was the same man in the ending of Iron  Man as in the beginning. His character development started and ended in that movie. Subsequent modifications in his nature were not part of his primary character development.
