HELP!! Atrribute Image Handling & Detail Image.

[Arquetipo]

Hello , I am new at zen-cart but learning as fast as I can.

I´m working on ; www.piperitahouse.com/menta/

I need help with 3 issues:

1) I am starting to work with attributes and with the dropdown option. Is it possible to swap the product Image so that it changes when you select differen attributes?
I have used different prices for each attribute bur the price in the page doesn't change at all.
Another pretty good option would be little thumbnails for each attribute like in: www.abercrombie.com/webapp/wcs/stores/servlet/category1_10051_10901_12270_-1_12203
Is this possible with Zen cart?

2) I want a "Detail" image beside the main image of the product info. I know how to manage multiple images but I would like to put a "Detail" written near the image.

3) I want to put reference number for each product, this number must be shown on the product info page. Any idea on how to do this?

Thank you very much for your Help.

Excuse me for the Abuse, I have two more questions:

1) How do I make the attributes obligatory? I mean that you must choose an atribute to buy the product.

2) Is it possible to include a Care Instructions section? A new field for products.

Thank you for your wisdom.
