Front page username, categories, and more...

So I was trying to disable certain things on the front end because I use the wanderers template and the mobile side of the wanderers template and it being responsive makes my site look very disorganized. When I disable them it does not seem to take them off the front page or the mobile site. Plus their is this use left and right arrow keys to in the upper right hand corner which also does not seem to go away. How do I disable these things and get rid of them from the front page?

I have included a attachment showing these things that I would like removed. I thought it was under the layout then listings area.
