Where did the Sketch tool go?

I am trying to convert my ArcObjects 9.3.1 code to 10. I have a simple button that when clicked creates a new shapefile & adds it to the TOC. It then starts the editor & selects the Sketch Tool.
The user then draws a polygon and the OnSketchEventHanlder then calculates the selected area the user just drew on the new shapefile. This is simple stuff but it wont work in ArcMap 10. Now I have to contend with what looks like templates & shapeconstructors. Ive managed to create a new template & add it to the template array, but I have no idea how to specifiy the editor to use the polygon construtor tool. The editor starts but the new shapefile is not selected & the polygon tools is not selected. How do I get it to use my template & use the polygon tool? Do i even need to do it this way with version 10? I see you can create a temporary feature within a template so I may not even need to create the new shapefile to use for editing???
Here's what I have so far

internal static IEditor get_Editor(IApplication application)
    IEditor editor = null;
    UID uidEditor = new UIDClass();
    uidEditor.Value = "esriEditor.Editor";
    editor =  application.FindExtensionByCLSID(uidEditor) as IEditor;
    return editor;

internal static void StartEditing(IApplication application, string layerName)
        IEditor3 editor = get_Editor(application) as IEditor3;

        //find the layer to edit
        IMxDocument mxDocument = (IMxDocument)application.Document;
        IFeatureLayer featureLayer = (IFeatureLayer)get_Layer(mxDocument, layerName);

        //check for existing templates & remove

        //create a single template for the editable layer
        IEditTemplateFactory editTemplateFactory = new EditTemplateFactoryClass();
        IEditTemplate editTemplate = editTemplateFactory.Create("PolygonAreaTemplate", featureLayer);

        //Add the template
        IArray templateArray = new ArrayClass();

       //Need some more code here use my template & use the polygon constructor tool

       IDataset dataset = (IDataset)featureLayer.FeatureClass;
