Not that I know of. But why do you need question shuffle if you already use random questions?

Suppose you have a certain image and 4 random questions relating to this image. You place the image in a description question and add it to the quiz. Then you add the 4 random questions. That's it. if you have several clusters such as this one you can use the quiz paging to place them in different pages. All that will work of course if you don't use shuffle questions. But you can still use shuffle within a question (to increase variation of MC).

Note the date of the post you replied to. With recent versions you should be able to achieve that by using letter grades or outcomes and without hacking the code.

4. It seems to me that a constant somewhere else is just as hardwired as a constant in the equation.
3. This may help reducing the number of auxiliary grade items so that if you have to make changes you go to one place.
   
1. Yes, but you still track them yourself by looking up a certain grade item in that category and updating it. Moreover, with one item for 'excused' and details in the item's feedback you can release this information to the students in the grade report without overloading the report with items.

Try adding to the assignment description the following code:

<script type="text/javascript">if(window.top!=window.self){var head=document.getElementsByTagName('head')[0];var style=document.createElement('style');var rules=document.createTextNode('div#header,div.navbar,div.headermenu,div#footer{display:none;}');style.type='text/css';if(style.styleSheet){style.styleSheet.cssText=rules.nodeValue;}else{style.appendChild(rules);}head.appendChild(style);}</script>

It works on Firefox. I haven't checked other browsers but even if it doesn't it shouldn't be too difficult to adjust.
