Tools
Download for WebApplicationProjectSetup.msi. This is an update to Visual Studio 2005 which adds a new project type that allows you to create web projects that reference explicit files like Visual Studio 2003 did rather than the default 'include everything in the directory' behavior that is/was default with Visual Studio 2005. Drilling down into this a bit more you'll find some additional resources on Scott Guthrie's web pages on web projects. (His main web site is here). This is outdated if you have Visual Studio 2005 Service Pack 1 as it is included in the Service Pack.
