Q

Cascade on updates and deletes

What if I don't want to use InnoDB? Does this mean I can't use cascade on updates and deletes?
FOREIGN KEY constraints (and the ON UPDATE ... CASCADE and ON DELETE ... CASCADE syntax that goes with them) are currently only available for InnoDB tables. While adding FOREIGN KEY constraints to MyISAM tables is on the development roadmap, I would not expect them in the near future. In short, InnoDB is your only choice at the moment.
