Where do I put JS?

Hi I am trying to integrate Longtail Video Ads w/my JW player using this module. The steps (code omitted) are:

"Step One: Add JavaScript tag
The first step is to add the following JavaScript tag at the BOTTOM of your page just above your ending tag. If you are using a CMS with separate template files, you should place the JavaScript tag at the END of the file that carries your Player code.

Step Two: Insert new div tags
The second step is to insert new div tags. The opening div tag should be placed BEFORE your player code and the closing div tag should be placed AFTER your player code."

Step Three: Edit your player settings
The last step is to edit a few of your player parameters, which will enable your player to serve ads through LongTail. These parameters are quite common, so you might have one or more already enabled.

Reference your website, along with the code below, to see what changes you need to make.

Note: Your embed code requires both

and tags for cross-browser compatibility. Please see the example and tutorial to the right for instructions. " Could someone please provide guidance as to where I can place this code? I am new to Drupal and PHP but am learning a lot messing with this idea I have for a site. Thanks :)
