Required brief document on JIRA to sell it to our internal stake holders.
It should have a small short story with all the advantages of using JIRA for project management.
Depends on what you actually want from it. Without knowing your stake holders, processes or people, I suspect you just need to start with http://www.atlassian.com/software/jira/overview - that's a brief document outlining what it can do, and there's some nice videos.
You might also want to try contacting Atlassian sales if you've got specific questions.
