Correct me if I'm wrong, but rules constrain the SQL (ie. validation).
Triggers are carried out after the SQL is executed and the data is modified.
So, to answer your question, I think rules come first.  As to which order
the rules / triggers are executed probably depends on the order you put them
in when you created them but I pulled that straight out of my arse.  :)
