How do i remove the name of the author or Company name from Title

Two Quick Questions:
1) How do I get it to not put the name or author behind each post. see below It is putting. " - Prime Law Group, LLC" after each title
2) Any tricks to shorten URL of the post so it is not as long.

Thank you,

Jim
