Title Text Size & Page Headings

Two questions:

1. How can I change the size of the text in the tiles. Example, on this page:
http://grabmypassport.com/news/ “Day Trip Ideas from Stuttgart” – I want that title to be smaller. Is that possible?

2. How can I removed the heading from each page. Example, on this page:
http://grabmypassport.com/about-me/ I want to remove the “About Me” at the top.

Thanks, Shannon
