Editing a little bit

So, i’ve changed what i could on the template, but i’m having some issues doing some modifications i want, on this: http://wordpress.dpfilmes.com.br/?cat=3 it’s a cat. page i’m using as a show-off for some videos, and i’m trying to firstly remove the date posted (like “April 24, 2013. In Filmes. By admin.”), remove that PERMALINK buttom and move the post text to the left of the video (where now is a empty sidebar), or if it;s not possible, just remove the empty sidebar and centralize the posts… But since i’m a newbie i couldn’t managed to do those changes by myself, i can provide the template/pieces of the code or whatever it’s necessary to get your help.

Already thankfull, Victor.
