Michael Howes is making his notes and resource list available on the web. In addition, he is willing to mail a CD-ROM of his slideshow to those who ask. (Link: Scroll to the bottom; PDF links are in the last paragraph)

I did not attend his workshop, but here is the description from the materials handed out at WALP:

Across denominations, some of the most adventurous leaders are engaged in church planting. You have a different, equally worthy dream: leading the established church you serve to new places of openness to God and spiritual health through worship change. But the landscape is strewn with wounded ministers who have attempted liturgical renewal and paid a high price. In this workshop, you will acquire some practical strategies to help you lead your church in seeking worship renewal without martyring yourself.
