I'm working on a custom data type for Umbraco based on Tim's Blog Post: http://www.nibble.be/?p=90

I've got it *mostly* working, but I need to include a colorbox (http://colorpowered.com/colorbox/) for one of my displays.  This requires jQuery, jQuery's colorbox, and a colorbox.css with a bunch of images.  Since it's a custom control, I can't just drop the items in a directory and link to them.  My control is called DoctypeSelector and here is the code as it is now:

using System;
using System.Collections.Generic;
using System.Web.UI.WebControls;
using System.Web.UI;

[assembly: System.Web.UI.WebResource("DocTypeSelector.Styles.colorbox.css", "text/css")]
[assembly: System.Web.UI.WebResource("DocTypeSelector.Scripts.jquery.colorbox-min.js", "text/js")]
[assembly: System.Web.UI.WebResource("DocTypeSelector.Control.DoctypeSelector.js", "text/js")]
namespace DocTypeSelector
{
    public class DoctypeSelectorControl : Panel
    {
        private HyperLink lnkSelector;

protected override void OnInit(EventArgs e)
{
base.OnInit(e);

if (lnkSelector == null)
             {
                lnkSelector = new HyperLink();
}

lnkSelector.Text = "Select...";
lnkSelector.NavigateUrl = "#";
lnkSelector.CssClass = "selectTool";

System.Web.UI.HtmlControls.HtmlLink cssLink = new System.Web.UI.HtmlControls.HtmlLink();
cssLink.Href = cssLink.Href = Page.ClientScript.GetWebResourceUrl(this.GetType(),"DocTypeSelector.Styles.colorbox.css");

            cssLink.Attributes.Add("rel", "stylesheet");

            cssLink.Attributes.Add("type", "text/css");

            this.Page.Header.Controls.Add(cssLink);

                 this.Controls.Add(new LiteralControl("<div style=\"display: none\"><div id=\"selectBox\">Welcome!</div></div>"));

            this.Page.ClientScript.RegisterClientScriptInclude(

                "DocTypeSelector.DoctypeSelector.js",

                this.Page.ClientScript.GetWebResourceUrl(typeof(DoctypeSelectorControl), "DocTypeSelector.Control.DoctypeSelector.js"));

            this.Page.ClientScript.RegisterClientScriptInclude(

                "DocTypeSelector.jquery.colorbox-min.js",

                this.Page.ClientScript.GetWebResourceUrl(typeof(DoctypeSelectorControl), "DocTypeSelector.Scripts.jquery.colorbox-min.js"));

        }

    }

}

It looks like the javascript and css are "attempting" to be embedded because i see extra links in the rendered page, but when I click them I get a:
