Changing Permalink for Q&A Plugin

Hi,

Several questions on this plugin:

1. The current permalink for this is: http://www.example.com/questions/ask. How do I change the permalink to something else?

2. The current buttons read: "Questions", "Unanswered", and "Ask a Question". How do I change the button text to something else?

3. Where do I add custom "introductory" text on the main "questions/ask" page?

Thanks.
