How about creating a ControlTemplate for your Marker Symbol, that includes TextBlocks, Line and Point?

For the TextBlock, you can create your own Converter for the Binding so that value can be transformed to a text with carriage returns. For example, "01" is transformed to "0\n1\n";

You said that the line will have a default size, right? With the point in the center of the symbol? I think customizing a MarkerSymbol's ControlTemplate will solve the problem.

You can look at the SymbolGallery for samples: http://help.arcgis.com/en/webapi/silverlight/samples/SymbolGalleryWeb/start.htm

Easiest way is to use ExpressionBlend to see how you want the symbol to look like and then change the properties to bind to Symbol.Size or specific Attribute.
