Admin Wizzard Plugin Suggestion

Hi !

For my SAAS project, I want to give my users the most simple experience in the Wordpress Admin.

I've checked what other SAAS do and I'm a huge fan of what Noel Tock and his team have done at Happy Tables. (http://www.happytables.com/)

Here, I'm looking for a wizard step by step plugin.
Here is what I want :
- Give users five "Things to do" on the dashboard.
- Have a progress bar that change depending on the number of steps which is completed.

Do you have any idea of plugin that can do one or more of these features ? Or a plugin that can act as a wizard or a step by step admin for users ? Or a plugin that can guide users ?

Thanks a lot !
