I've read all the books you mentioned other than Slapstick and agree with your synopsis and recommendations.
I'd personally start with Cat's Cradle over Slaughterhouse Five. Deadeye Dick is strange and hilarious, but probably better after reading a few of his books first. :)

Probably true about Bluebeard, too. Both read almost as a review of the major themes and messages of Vonnegut's work, though Bluebeard more so than Deadeye Dick.
