@fritzhesse: Yes you can use “Custom CSS” or child stylesheet to change the font of the test in the menu bar. Try use Web safe fonts http://www.w3schools.com/cssref/css_websafe_fonts.asp. For example to change to Arial font you can add as below:
#header-menu { font-family: Arial, Helvetica, sans-serif; }
Yes it requires Pro version. If you have Catch Everest Pro theme, you will have option of Footer Editor box in Theme Options panel though which you can easily remove the “powered by wordpress” text.
