I think it is a good series of SharePoint 2007 Workflows for the beginner.
Table of Contents for on SharePoint 2007 WF Authoring using VS2005.
1. Setting up your environment for writing VS2005 workflows.
2. Writing an ultra basic workflow, deploying it, and slicing dicing how it worked.
3. Making that workflow more complex, adding if/else, and a bunch of activities that sort of make it more interesting.
4. Adding user interaction to that workflow using Infopath forms.
