Microsoft has released a new set of code snippets for Visual Studio 2005 for developers who are building around the Office 2007 UI. 

From the download site:

Overview

This download includes Microsoft Visual Basic and Microsoft Visual C# code snippets for use when customizing Microsoft Office Excel 2007, Microsoft Office PowerPoint 2007, and Microsoft Office Word 2007. Download and install these snippets to your Visual Studio code snippet folder and use them with the Visual Studio Code Snippets Manager.

Even if you don't currently do any Office 2007 development in Visual Studio 2005, I would recommend that you download them anyway.  They are free (in both Visual Basic and C# languages) and you never know what your next project will be. :)
