Question

The below file contains all the javascript for a page. Performance is the highest priority. Is this the most efficient way? Do all click/hover events need to to be inside the doc.ready?

//DOCUMENT.READY EVENTS
//---------------------------------------------------------------------------
$(function(){       

        // mark events as not loaded
        $('.event').data({
            t1_loaded: false,
            t2_loaded: false,
            t3_loaded: false,
            art_req: false
        }); 

        //mark no events have been clicked
        $('#wrap_right').data('first_click_made', false);


        // cal-block event click
        $('#cal_blocks div.event, #main_search div.event').live('click', function(){
            var id = $(this).attr('id').split('e')[1];  
            event_click(id);
        });

        // jq history
        $.historyInit(function(hash){
            if(hash)
                {
                    event_click(hash);
                }
        });

        // search
        $('#search_input').typeWatch
            ({

                    search(q);

Answer 1

to be sure that all DOM elements already created properly you have to work with them only in document.ready. so the code is fine.
