1. No, but you can easily enable it by yourself by choosing option "(2) I want to customize my Nginx installation. (for advanced users)" in passenger-install-nginx-module. Arbitrary Nginx configuration is fully supported. We're going to enable SPDY by default in a future versions.
2. Yes. Phusion Passenger 4 fully supports Ruby 2.0 so it doesn't prevent you from using it, but you may run into Ruby 2.0 bugs, e.g. https://bugs.ruby-lang.org/issues/8100. We recommend staying with 1.9.3 until the next Ruby 2.0 patchlevel, but the choice is yours.
