I think (IRC) you have to register with the website they're found on and/or pay a bit of cash, though I'm not sure and the website seems to be down at the moment...
I couldn't access the pages but I can now so have confirmed what I thought.
If you scroll to the bootom of the test pages there is a bit of text which says: "An answer sheet is only provided for free registered users of jlpt.info."
Hope that helps.
As for the listening part of the test, there's an audio file embedded into the page.
These contain past papers more than 5 years ago. The format of the exam has changed very slightly since then so for new ones with better quality, please contact you nearest Japanese language bookshop.

I'm very sorry the links I gave you now don't work but they were working only a few days ago. Very strange.
A friend of mine pointed this out just now that the links weren't working.
