Newbie questions and toddler suggestions

hi,

I saw the template library and I was "megally" impressed, Nice work. But I have some newbie questions as I am new with CI (only done 2 basic sites) and my third I want to use template.
Q1: Adding utilities i understand but I wanted to know if I have 4 js files and 4 css files and add them, how does template know which to use where i need it? example I have a .js file for displaying the current time, will know it's that one I want and not the jquery.js file i have?
Q2: I have my js and css files in an assets folder in my project but I also have images for all my images, so my question is, will this code work if I add it to the template library if my first question's answer is "yes template can figure out what I want some how".

Code:

function add_image($imgfile)
   {
      $success = TRUE;
      $img = NULL;

      $this->CI->load->helper('url');
      $filepath = base_url() .$imgfile;

      $img = '<img src='.$filepath.'/>';

      // Add to js array if it doesn't already exist
      if ($img != NULL && !in_array($img, $this->img))
      {
         $this->img[] = $img;
         $this->write('_images', $img);
      }

      return $success;
   }

i simply modified one of the functions for images. Any thoughts?
