The office group has released a White Paper on how to build business solutions on top of SharePoint/MOSS 2007. I just read through it, and it's not bad for a whitepaper. It's a descent reference document with a little bit of how to and a bit more of "how things are to be done".
Here's the description from the site:
Learn how to build a business solution leveraging a broad range of Microsoft Office SharePoint Server 2007 Enterprise capabilities. This white paper focuses on the real-world example of an application to help consulting companies track client engagements and business performance. But the insightful lessons learned and best practices will apply wherever your next SharePoint development project takes you.
Topics include Office SharePoint Designer 2007, workflows, Excel Services 2007 and the Enterprise Search API. Whether you are a SharePoint development guru or a Microsoft .NET developer evaluating the platform, this white paper has something for you.
