Yes, you'll need to create a database and a database username.  How to do this varies from server to server.  Basically, you log into your host account, and go to the section where you administrate "MySQL Databases" or something similar.  On some servers, your database username and password is the same as for the host account.  On other servers, you need to create a unique name and password to access the database.  Then, you just need to create a database and give it a name.  All this information is then typed into the installer.

The Database hostname is almost always "localhost", so you probably don't need to change that.

The encryption salt reduces the likeliness of someone hacking another person's account.  You should use some other unique 2-character code for the best results.  However, make sure you write down whatever you choose for the salt, because if you forget it, there's a possibility that nobody will be able to log in anymore, and they will have to create new accounts.  If that ever happens, I can help you fix it.

I took another look at the image you posted, and it appears that they have a dedicated computer for SQL, so "localhost" isn't going to work.  Try this:

Database Hostname: sql113.php0h.com
Database Name:     (whatever you called it)
Database Username: p0_5089359
Database Password: (whatever you called it, or the same as your cpanel password)
