All, I was finally able to spend some time to answer my question about how to specify which Web site on the IIS server I wanted to create the Virtual Directory for. In the following line of code, the "1" is the identifier for which Web site you are referring to. You can get this number by left clicking on the Website folder. To the right, the screen should now list all of your Web sites and there is an identifier column. That is the value that should be there.

Dim IISAdmin As New System.DirectoryServices.DirectoryEntry("IIS://" & WebSite & "/W3SVC/1/Root")

Hope that makes sense.
