How to show product total price calculation in Magento cart

I'm having problems trying to show the product full total price in Magento, and by product total price I mean full product price without the discount; the price has to be multiplied for each product quantity added to the cart, and custom options additional price should be added as well. Which files should I edit in Magento? is it possible to show the product discount inside the cart (amount that varies with the amount of ordered products)?
Thanks
Edit:
screenshot
In the blue rectangle it shows the regular price, which should be regular price X 2 (since product quantity is 2) with added 122€ as chosen in product special options. Instead now it shows regular price with discount applied and for only 1 product, without special option added.

Magento discount to multiple categories without discounting SKU?

I am applying a price rule to whole categories in my Magento store but I want to leave out a few of the items within the discounted category.
How can I do this in the price rules?
I have tried everything and it just discounts all the products and still discounts the products I want to leave at full normal price.
Thank you so much!
You can accomplish this with Shopping Cart price rules.
In the Actions section, under "apply the rule to the items matching this criteria":
