change the product page

i am working with a 1.3.8a version of the site, without any teamplates.
i would like to know how to modify the product zone of the page to look diferent then usual. by default the page contains a picture, the price, the quantity, and the description area. mine is now as seen in the link:

http://www.uragan.ro/2/index.php?main_page=product_info&cPath=2_14&products_id=7

and i would like it to look something as this for example:

http://www.emag.ro/carduri_memorie/card-memorie-kingston-secure-digital-2gb--pSD2GB

what files are implicated in the way this area looks like?
thank you very much

anybody please, at least some hints so i can figure a way to head it.

Add the following to your stylesheet and adjust as desired
You will most likely have to adjust the clears in tpl_product_info_display.php for further refinement
And to border all with one border add a div that contains all items wanted inside the border

#productName {
margin: 0em 0em 0em 20em;
width: 55%;
}
#productPrices {
margin: 0em 0em 0em 22em;
width: 55%;
}
#productDescription {
border: 1px solid #cacaca;
margin: 0em 0em 0em 25em;
width: 55%;
}
#productDetailsList {
margin: 0em 0em 0em 30em;
width: 55%;
}

i have a new question on the page i am working on. how can i move the productDescription box from the right to the left of the tpl_product_info_display.php page. i have the exemple here http://www.uragan.ro/2/index.php?main_page=product_info&cPath=2_14&products_id=7.
thank you

and i also want to introduce more description boxes in admin page and product info page what and where do i have to modify?
