If create a custom content query webpart you should be able to pass an argument into the XSL via the XslCompiledTransform.Transform() method.  This takes in a XslArgumentList which you could populate with the editorpart properties.

By the way ToolParts are the old version you should use EditorParts http://www.thesug.org/blogs/lsuslinky/Lists/Posts/Post.aspx?List=ee6ea231%2D5770%2D4c2d%2Da99c%2Dc7c6e5fec1a7&ID=8 and webparts should inherit from System.Web.UI.WebControls.WebParts.WebPart class.

 

Override ModifyXsltArgumentList and add the custom parameter to the argument list: 

protected override void ModifyXsltArgumentList(ArgumentClassWrapper argList)
{
    base.ModifyXsltArgumentList(argList);
    argList.AddParameter("ParameterName", "", "ParameterValue");
}

Once this method runs the new ParameterName is then available for use within the xslt.
