Everyone has pretty much answered the questions...as for people hating New Krypton, New Krypton and everything prior to it are leading to a much bigger story arc that will be taking place in the major 2010 Superman arc in the summer time. I started a speculative thread a couple months ago about what might happen.
Dick is indeed Batman...Dick assumed the role of Batman in order to preserve the legacy and mythos of Batman. Tim assumed the role of Red Robin because he didn't want to tarnish the role of Robin (he's got a very negative view on Damien and Jason Todd). He's been off searching for Bruce Wayne in his own book and has made allies of...interesting people.
