Do the original tarokka deck work for Curse of Stahd?

Are the random encounters in Curse of Strahd intended to have treasure according to their CR?

Curse Of Strahd is my first campaign that I’m DMing, should I read ahead to learn everything?

The deck of many things or Tarocca Deck?

In Curse of Strahd would you stop a character from simply taking every dark gift?
