I announced the release of v1 of the VSTO/VSTA Power Tools last time, and they've been getting quite a bit of use so far. The downloads are here - these include an overview document. Note that the documentation for the individual tools is installed in the same folder where you install the tools themselves.
Phil Hoff, who was one of the developers working on the Office Interop API Extensions library has a number of very interesting blog posts, and I encourage everyone to check them out - there's lots of useful information in these posts, and I hope Phil will keep them up.
