Answer 1

If you want to run bitmap reports (PDF/Postscript etc) you must have X server of some description... If you are on later version of apps is is mandatory.
Does you server have a monitor, if so native X server will be running, if not you'll need to run an X server (xvfb or vncserver) somewhere - you could run XMing (or Reflection) on your client set DISPLAY to your_client:0.0 and connect to that but not for anything other than development.
