I worked in the HOLs for Launch, I thought that the labs were pretty good.  Particularly these for VS2008:

WCF & REST; WCF & WF; C# 3.0 Language Enhancements.

I also liked these SQL Server 2008 labs:

Change Data Capture; Policy-Based Management; DATE/TIME Data Type; Spatial GEOGRAPHY; Plan Freezing
