The Yucatan prologue was likely dropped because there's very little action. It would've basically meant re-introducing Indy by...having him crawl on his stomach. Since they were able to explain the entire scene with just a few lines of dialogue, they probably never even shot it.
According to Lucas, the decision to start the film with Indy in the trunk served two purposes. First, it was the polar opposite of his introduction in Raiders, where he confidently stepped into camera view. Second, it was a way of taking the character out of mothballs after 19 years- both literally and figuratively.
I thought the best part of the book was the way it handled the finale. It made the lost city feel much more fantastical and epic in scope.
