The ECM Starter Kit updated for B2TR is in the process of being published to MSDN. But in the meantime, just thought I'd post an "unofficial" version.
The samples are pretty much the same as in the Beta 2 kit, but there are a few additions:
Whitepaper: How to Add Activities to SharePoint DesignerRecords Management Sample: Sample Barcode GeneratorECM Workflow Activity: FindManager activity
Also, the workflow templates come with some WSP solution package files to help with bundling workflows for deployment on production servers.
Hope this helps:)!
