I have goggled about this, found so many blogs but nothing worked as I was expecting, finally found my own successful way to 'Add New Item' / ‘Add new Announcement’ / ‘Add Document’ / 'Add New Discussion' to all list and libraries in SharePoint on Top of page.
var addButton = $(this).find("td.ms-addnew").html();
if(addButton != null)
{
$("div#WebPartWPQ2 td:first").prepend("<div style='margin-top: 12px;'> "+addButton+"<br/><br/></div><div class='ms-partline' ColSpan='2'></div>");
}

and if you want To Hide Add New Item link button in sharepoint 2010 list of library
below information source : Raviraj
On home page add lists/libraries that you want and then select edit webpart and set toolbar
type to "No Toolbar".
Or you can add style:
.ms-addnew{
display:none;
}
on home page.
Make sure that ribbon is hidden
or try this on home page.
.ms-cui-row-onerow{
display:none;
}
