A few changes in my shop layout! Need help

hi,

1. checkout card
   I want to implent a new checkout card box into my not finished shop.

https://www.itamz.net

The problem is that Im ye...a noob at this :)

Here is that what I expect, I found it on another site and I want a similar on my site.

2. I want to remove the article description totally. So when somebody clicks on the picture or on the prodcut he will not get to the description. But I want if the costumers clicks on one of those that he gets a pop up with a picture

very nice to check here what I want

3. Changing article amount into a drop down

I want that the costumer can choose the amount with a drop down. In my shop atm he has to write it manually.

4. "Add to card" button under the price
   again very nice example here: http://www.vritems.com/d2/1/index.html

5. And then I have a question about a picture. I want to add flags for my categories.But Im not sure If I am allowed to use unmodified flags for that. I mean I take an US flag and an EU flag...does somebody knows something about this?

ok...these are the first changes I want to do, I hope somebody of you can help me...maybe somebody can help me a little bit more for some extra cash..I dont know if this is allowed here to offer...if not I'm sorry.
