I installed a windows update for Silverlight on my Win 7 64-bit PC yesterday, and today when I started VS 2008, I got the following error:
---------------------------
Microsoft Visual Studio
---------------------------
Package Load Failure
Package ‘Microsoft.VisualStudio.Silverlight.SLPackage, Microsoft.VisualStudio.Silverlight, Version=9.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a’ has failed to load properly ( GUID = {CB22EE0E-4072-4AE7-96E2-90FCCF879544} ). Please contact package vendor for assistance. Application restart is recommended, due to possible environment corruption. Would you like to disable loading this package in the future? You may use ‘devenv /resetskippkgs’ to re-enable package loading.

Yes No

Is there an update for the VS integration as well?

Take a look at the blog about a June update to Silverlight. Consider downloading and installing the Windows Developer Runtime that Tim provides a link to.
The update may have installed the standard runtime but dev machines need this developer version of the runtime.
