Confused About Jquery And Script Inclusion Handling

I am totally confused about Yii's handling of jquery and other javascript file inclusion.

This was working:

<script type="text/javascript">
    jQuery(document).ready(function() {
        jQuery('#Event_recuring_nature, #Event_venue, #Event_expected_attendance, #Event_age_group, #Event_state, #Event_gender, #Event_ethnicity, #Event_exclusivity, #Package_cash_product_sponsorships, #Event_vanue_signature, #Event_logo_on_step_and_repeat, #Event_inclusion_in_press, #Event_ad_space, #Event_inclusion_in_event_materials, #Package_category_exclusivity, #logo_on_signature, #Event_proposed_events_included, #Event_dependant_on_sponsorship, #Event_sponsorship_type, #Event_attendee_professions, #Event_attendee_income').yaselect();
    });
</script>
<script type="text/javascript" src="/js/libs/jquery-ui-datetimepicker.js"></script>
<script type="text/javascript" src="/js/event_create.js"></script>
<script type="text/javascript" src="/js/slider.js"></script>
<script type="text/javascript" src="/js/other_social.js"></script>
<script type="text/javascript" src="/js/package.js"></script>

while this (which supposedly would be better?) does not:

<?php 
Yii::app()->clientScript->registerScript('create-script', "
    $(function()  {
    	  $('body').css('overflow-x','hidden');
        $('#Event_recuring_nature, #Event_venue, #Event_expected_attendance, #Event_age_group, #Event_state, #Event_gender, #Event_ethnicity, #Event_exclusivity, #Package_cash_product_sponsorships, #Event_vanue_signature, #Event_logo_on_step_and_repeat, #Event_inclusion_in_press, #Event_ad_space, #Event_inclusion_in_event_materials, #Package_category_exclusivity, #logo_on_signature, #Event_proposed_events_included, #Event_dependant_on_sponsorship, #Event_sponsorship_type, #Event_attendee_professions, #Event_attendee_income').yaselect();
    });
   
");
?>
<?php Yii::app()->clientScript->registerScriptFile($this->assetsBase.'/js/libs/jquery-ui-datetimepicker.js'); ?>
<?php Yii::app()->clientScript->registerScriptFile($this->assetsBase.'/js/event_create.js'); ?>
<?php Yii::app()->clientScript->registerScriptFile($this->assetsBase.'/js/slider.js'); ?>
<?php Yii::app()->clientScript->registerScriptFile($this->assetsBase.'/js/other_social.js'); ?>
<?php Yii::app()->clientScript->registerScriptFile($this->assetsBase.'/js/package.js'); ?>

I had
<app_dir>/js/ for all javascript and created
<app_dir>/protected/assets/js as suggested in a post on this forum for registerScriptFile
I had of course duplicated files and I am cleaning up.

The layout has this in the header:

        <?php Yii::app()->clientScript->registerCoreScript('jquery')?>
        <?php Yii::app()->clientScript->registerScriptFile($this->assetsBase.'/js/libs/jquery-ui-1.8.20.custom.min.js')?>
        <?php Yii::app()->clientScript->registerScriptFile($this->assetsBase.'/js/libs/jquery.yaselect.min.js')?>
        <?php Yii::app()->clientScript->registerScriptFile($this->assetsBase.'/js/script.js')?>

and I have this in config/main.php:

// application components
	'components'=>array(
		'clientScript'=>array(
					'packages'=>array(
							'jquery'=>array(
									'baseUrl'=>Yii::app()->request->baseUrl . '/js/libs/',
									'js'=>array('jquery-1.7.2.min.js')
					)					
				)
		),

(I know that baseUrl is now pointing to <app_dir>/js, but trying with

'baseUrl'=>Yii::app()->basePath . '/assets/js/libs' 

also did NOT load jquery at all!!!

PLEASE HELP! I am new to Yii and am loosing my mind on this. Thank you.
