Answer 1

Thariama's answers was awesome just implemented it and it was just what I was looking for, just made a few modifications:

    max_chars : "10",
    setup : function(ed) {
        ed.onKeyDown.add(function(ed, evt) {
            if ( $(ed.getBody()).text().length+1 > ed.getParam('max_chars')){
                evt.preventDefault();
                evt.stopPropagation();
                return false;
            }
        });
    } 

Thanks Thariama.
