Oracle has a java-based GUI for server installation. There are some scripts that need to be run as root, which you will be informed of during the installation process. Read the Oracle installation documentation. It is not simple, but the docs are generally quite thorough.

Username/Password for what? For your local Oracle database and/or user account?

You need to know the password for the system oracle account, which you specify I think when you install the database, though it may just default to "oracle". Login to the oracle account, and you can create any number of new dba accounts in the database.
