Portoflio Grid

Hi, I am using a portfolio grid with display style ’9′. It looks like this one:

http://themeforest.net/item/fortuna-responsive-multipurpose-wordpress-theme/full_screen_preview/12496833

I want to do three things with it, remove the subtitle, remove the camera icon and make the white overlay have no padding so it goes to the edge of the image.

I have managed to get rid of the subtitles with this CSS:
a:hover .pic_info.type9 .info_overlay p {
display: none;
}

However, I can’t seem to do the other two things, I’ve tried different bits of CSS but none of them seem to work.

Many thanks for your time
