I must had some jquery files and stylesheets towards the mind from the tinyMCE editor of wordpress. Any suggestions regarding how to do that?

Make use of an own wordpress plugin or even the tinymce setup paramter

// Adds an observer to the onSaveContent event using tinyMCE.init
tinyMCE.init({
   ...
   setup : function(ed) {
      ed.onInit.add(function(ed){
         ed.dom.loadCSS( 'url_to_your_css_file' );
      });
   }
});
