Do you need to have incremental video files for each "step" in bandwidth?Or does the Silverlight server dynamically steps down the resolution?

Smooth Streaming is enabled by IIS 7.x, not Silverlight. This is a free value-addition to Windows Server 2008.
Smooth streaming is also known as adaptive streaming. The host that serves the media file has the file encoded in several different bit rates. These are delivered to the client via HTTP in a series of "chunks". If the bandwidth is slow the Silverlight client can play the "lower" bitrate version automatically (since it simply skips to the lower chunk that is delivered). This is why you get the name smooth streaming.
Expression Encoder 3 can automatically encode the various bit rates ready for hosting for IIS 7.x smooth streaming. Therefore, you won't have to manually do this 4x or something like that.
