Change (alter) price before or after order is placed (partial refund / extra freight)

I've got a client I've designed an e-commerce site for, and we are in the final stages where he just has a few more tweaks, and I've been searching on the forums for over an hour trying to find this problem, but can't find a solution :\

Relevant info:
Latest version of Zen Cart (v1.3.8a)
Site: http://www.fjfantasy.com
Modules installed that are relevant to these problems-
Super Orders
Ultimate SEO URLS
LinkPoint gateway for Credit Card Transactions
PayPay Express for Paypal

Problem 1: Discount Coupon Codes need to be invisible to customers

He wants the ability to discount someone dynamically (any amount he chooses at any given moment) from an order before the user places the order. I installed the Discount Coupons, but he does not want the user to know what the code is for the discount coupon code. (It shows up on the invoice and also the user's account I believe). He doesn't want people to know because they will be able to use the coupon code to figure out how to automatically get $5-50 off their next order and that's not good. I need to find a way to hide the actual code from the user. Why would we want to do that? Because with phone orders, the Admin logs in AS THE USER, and places the order there and he knows the coupon code, but we don't want the customer to know it.... Super Orders allows us to change the Invoice in the E-Commerce site, but it doesn't credit the user's credit card.

Problem 2: Charge extra shipping after order

This is the exact opposite of the problem above, he wants to be able to add extra freight for Canadian orders but not using any formulas, it's based off what he thinks he needs to charge extra (arbitrary) Right now shipping is set Per Unit, and every item has a custom Shipping price, and he is not using Calculated postage modules, nor does he want to. Super Orders allows us to change the Invoice in the E-Commerce site, but it doesn't credit the user's credit card.

(bonus) Problem 3: SSL certificate is supposedly installed, but not working when turned on in Zen Cart

Right now, if I go to my site and use any address with https, it automatically redirects me to a file called: nddbc.html

When I turn on SSL, the site does not work. Can anyone point me to a topic that deals with something like this? I think it has to do with the Ultimate SEO URLs module as that stops working when this is turned on.

ANY HELP WOULD BE GREATLY APPRECIATED!!!

Ok, we have figured to add shipping, we are just going to add in the extra amount to the current order on Zencart, and physically add in a new charge to the customer's credit card via their POS gateway.

I edited out the Discount Code from the Invoice, and it automatically erased it from everything except now you can still click on the word "Discount Coupon" and it pops up with which coupon they used, so I still need to eliminate the fact that that is clickable...

The only thing left is that stupid SSL certificate. Can anyone point me in the right direction there? Here is my config files:
