Answer 1

Use!

public class MvcApplication : System.Web.HttpApplication
{
    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapRoute(
            "User",                                                     
            "User/{domain}/{username}",                           
            new { controller = "User", action = "Index", username= UrlParameter.Optional }      
        );

       }

    protected void Application_Start()
    {
        RegisterRoutes(RouteTable.Routes);
    }
}

Answer 2

Your User controller should have

public class UserController : Controller {
    public ActionResult Index(string domain, string username) { return View(); }
}

The two variables on the Index method of the user controller get picked up from the route.

MapRoute() is an extension method over Routes.Add(). Use MapRoute(), unless you need to do something more complex than it allows.

Routes are evaluated in the order they are defined, so those you called first.
