Answer 1

First of all, Id use the plugin event:

function onBeforeRender(){

}

Secondly your path is pointing wrong.

Change it to:

//J1.6+
$script= JURI::root(true).DS.'plugins'.DS.'system'.DS.'sjdinfinitescroll'.DS.'jquery.infinitescroll.js';
$document =& JFactory::getDocument();
$document->addScript($script);

If you have MooTools loaded on the same page, you have to use jQuery.noConflict(); to avoid conflicts.

All together:

function onBeforeRender(){
      $script= JURI::root(true).DS.'plugins'.
           DS.'system'.DS.'sjdinfinitescroll'.DS.'jquery.infinitescroll.js';
      $document =& JFactory::getDocument();
      $document->addScript($script);
      $document->addScriptDeclaration('jQuery.noConflict();');
      $document->addScriptDeclaration('jQuery(function($){ $('#myid'.append('<h2>my header</h2>');} );');
}
