Oxygen Theme – removing items from front page

Hi, I would like to remove the gray boxes and the text inside them that appear on the front page of the Oxygen theme.

1st gray box says “Recent Articles” and the 2nd gray box says “More Articles. I would like those gray boxes and the text they include to be removed, but I cannot figure out how to do that.

Also, On the slide show, I don’t want the post title to appear on the picture. Currently, when the slider/featured picture appears, it says the title of the post along with the date below it to the right of the slider picture. How can I remove that? I just want to the image to appear. No text.
