Quick item that I'm sorry I missed. Microsoft released the Silverlight 1.1 Tools Alpha for Visual Studio 2008 so you can start building Silverlight apps with the shiny new Visual Studio. According to Don they aren't available for Visual Studio Express but it sounds like he's going to be doing some posts on how to do development with VS2008 Express and Silverlight.
Also according to Scott we'll be getting some info on the next public version of Silverlight 1.1 soon. It's been kind of radio silence on that front for a while as Microsoft released 1.0 but with Mix coming up next year, expect to see a lot more Silverlight 1.1 news flowing.
