Not to be snide, but the answer to questions 1 & 2 are "it depends".
Depends on the servlet runner - this behavior isn't spec'd. You
shouldn't really rely on it behaving in any specific manner - RTFM for
your engine.
Questions 3 + 4 are answered in almost every book on servlets. init is
called by the server, like main is called by the VM. Init parameters
are passed in from the admin interface of the server.
