There is a book with the script and some writings about the show. Look around. Check Abebooks.com or some other book search site.
To make the show work, three or four parts have to be done well: the opening which sets the entire evening up, the wireless scene, the Strauss' scene and the ending.
As for the physical production:
The ship is the main 'character' in the show yet it is never seen whole except in a small model. Parts of the ship are suggested. If the ship is not considered the lead role, your production may have problems.
As for the ship sinking, it was the best thing in the show because it was done so simply and any theatre company can do it the way it was done on Bway as long as it is done quickly.
Don't worry about the tilting set. That's what you have a design team for.
