No,
.Net is not about programming for internet, probably having "Net" in name confuse people. .Net is about programming for anything, be it internet, desktop, mobile ...
.Net classes for creating internet applications are mostly in a namespace called ASP.Net. From first version of .Net you can create web application. However web applications are thin client far away from desktp applications' rich interactivity. That's where Silverlight comes into a play. You can think of it as a plugin/extension. Here is how MS describes it:
"Microsoft Silverlight is a cross-browser, cross-platform plug-in for delivering the next generation of .NET-based media experiences and rich interactive applications for the Web."
Wikipedia has a broad description:
http://en.wikipedia.org/wiki/Microsoft_Silverlight

To understand why Silverlight 2.0 is important you should have seen older versions (like evolution of foxpro) of .Net + Atlas/AJAX, silverlight 1.0. It's along the lines of bringing windows presantation to any platform through browser applications.
