Tools and Techniques for agile projects

Thanks for your suggestions everyone. I think I’ll look into Mike Cohn and managing the team further.
To be a little more clear I’m a CSM and PMP. The organization in which I am working is a start up so that tells you a lot about the culture. They use jira and the standard artifacts and meeting associated with scrum to manage professional services projects, however, the issue I am having is that I can tell the customer feels that we’re not being transparent enough in our weekly meetings. That said, I was hoping to hear about the tools and techniques my fellow PMs are using to show their customers what the progress is on software projects. I understand I have to be comfortable with ambiguity to an extent and there isn’t supposed to be an emphasis on documentation in agile projects. I’m just wondering how you all do it in your organization. What best practices have you found effective.
