Help with fixed content (joomla) in PrestaShop

[PrestashopTrackglobe]

I have the website with Joomla adoptions / adoption / (www.eluniversodelperro.com/adopciones/) and I would like to keep the same design as the store. Because users is a mess, I just want to keep the categories already created and the articles (reviews of the same only if you can).

For now I've created a kind of pestal you get the categories, articles, etc and add new, but of course the thing is that after I show them so easy and I make the friendly URL like this: / adopciones/categoria1/categoria2 ..... / nombrearticulo.html
and this bitch I have no how.

Maybe not, the other idea you can think how I can do this by CMS or so (but be aware that ALL items that I want to comment, etc).

PS: Do not recommend because it serves JFusion, the same creators told me they could only be done if I programmed them to 0, as JFusion not allowed. (The same with PHPBB3 and Prestashop).

I would like to know how to put the button I like about Facebook that appears on products (sheet) in the CMS (I say this by paragraph 1 of Joomla and Adoptions).
