ScriptUI Panel Resource String Question

I'm creating a little tool to use to keep my projects organized, and want to create a dropdown that will eventually list off render templates I have created. Right now, for testing purposes (since I'm brand new to ExtendScript), I'm just trying to pass a pre-created array from a function so I can build in the code to access the Render Templates later.

{
function joshPipe(thisObj){
    function joshPipe_buildUI(thisObj){
        var pipePanel = (thisObj instanceof Panel) ? thisObj : new Window("palette","Josh Pipeline", undefined, {resizeable:true});

        var rsdPath = 'Workspace not loaded';
        var presetList = ['Render Template 1','Render Template 2','Render Template 3'];

        function getPath(){
            return "Project Loaded";
            }
        function getPresets(){
            list = ['Render Template 1','Render Template 2','Render Template 3'];
            return list;
            }


        queueTab = "group{orientation:'column', alignment: 'fill', alignChildren:['fill','fill'],\
                    group0: Group{orientation:'column', alignChildren:'fill',\
                            loadPipeButton: Button{text:'Setup Workspace'},\
                    },\
                    group1: Panel{orientation:'row',text:'Render Settings',alignChildren:['fill','fill'],\
                        group1_1: Group{orientation:'column', alignChildren:'left',\
                            fullRadioButton: RadioButton{text:'Full (Delivery)'},\
                            halfRadioButton: RadioButton{text:'Half (Review)'},\
                        },\
                        group1_2: Group{orientation:'column', alignment:'right',\
                            renderTemplateDD: DropDownList{properties:{items:['Template 1','Template 2','Template 3']}},\
                        },\
                    },\
                    group2: Group{orientation:'column', alignChildren:'fill',\
                            rsdString: StaticText{multiline: 'true', text:'"+rsdPath+"'},\
                            renderButton: Button{text:'Setup Render',},\
                    },\
                }}";


        pipePanel.grp = pipePanel.add(queueTab);

        var loadPipeCtrl = pipePanel.grp.group0.loadPipeButton;
        var fullRenderSelCtrl = pipePanel.grp.group1.group1_1.fullRadioButton;
        var halfRenderSelCtrl = pipePanel.grp.group1.group1_1.halfRadioButton;
        var renderTemplateDDCtrl = pipePanel.grp.group1.group1_2.renderTemplateDD;
        var rsdStringCtrl = pipePanel.grp.group2.rsdString;
        var renderButtonCtrl = pipePanel.grp.group2.renderButton;

        loadPipeCtrl.onClick = function(){
            rsdPath = getPath();
            rsdStringCtrl.text = rsdPath;
            renderTemplateDDCtrl.item[0] = 'yo momma';
            }

        renderButtonCtrl.onClick = function(){
            rsdStringCtrl.text = 'Project Unloaded';
            }



        //Defaults
        //pipePanel.grp.group1.group1_2.renderTemplateDD.selection = 0;

        //window size
        pipePanel.layout.layout(true);
        pipePanel.grp.minimumSize = pipePanel.grp.size;

        //panels resize
        pipePanel.layout.resize();
        pipePanel.onResizing = pipePanel.onResize = function(){this.layout.resize()};

    return pipePanel;     //Returns final result of pipePanel
    }
    var pipeScriptPal = joshPipe_buildUI(thisObj);

    if((pipeScriptPal != null) && (pipeScriptPal instanceof Window)){
        pipeScriptPal.center();
        pipeScriptPal.show();
    }

}

joshPipe(this);
}

The rub is that want this tool to be a panel that I can dock. As near as I can tell (using David Torno's Extendscript series as my guide) I have to read in the UI and its options initially as a resource string, and I can't figure out how to make it work. Any suggestions?
