Answer 1

why not select active tab first then active the selected tab content ?
1. Add class 'active' to the < li > element of tab first .
2. then use set 'active' class to selected div.

    $(document).ready( function(){
        SelectTab(1); //or use other method  to set active class to tab
        ShowInitialTabContent();

    });
    function SelectTab(tabindex)
    {
        $('.nav-tabs li ').removeClass('active');
        $('.nav-tabs li').eq(tabindex).addClass('active'); 
        //tabindex start at 0 
    }
    function FindActiveDiv()
    {  
        var DivName = $('.nav-tabs .active a').attr('href');  
        return DivName;
    }
    function RemoveFocusNonActive()
    {
        $('.nav-tabs  a').not('.active').blur();  
        //to >  remove  :hover :focus;
    }
    function ShowInitialTabContent()
    {
        RemoveFocusNonActive();
        var DivName = FindActiveDiv();
        if (DivName)
        {
            $(DivName).addClass('active'); 
        } 
    }
