Making Adjustments to Stylized_Beauty THEME - HELP!

I am using the theme stylized_beauty and want to make a few adjustments.

First, I want to give credit where credit is due, however the designed by __________________ links at the bottom of the page are annoying. I was wondering how to change the bottom tags to something more innocuous and subtle.

I was also wondering if it is possible to have this theme set up for a wider screen shot.

Help me if you can? THANKS
