Use $(element).height() to determine the height of the elements (such as the "comment box"). Use this value to change to position of your tools, eg:

var offset = $("#comments-box").height();
var mytoolbox = $("#myToolbox");

offset = offset+20; // Function logic (example). Adjust this line to meet your wishes
mytoolbox.css("bottom", offset+"px"); //In conjunction with `position:fixed`
mytoolbox.css("top", offset+"px"); //When used in conjunction with `position:absolute`

You could use jquery scroll() and then react accordingly. But you should provide some code so that we could help you more
