Questions about Ultimate SEO URLs installing

I'm installing Ultimate SEO URL and got two questions about INSTALLATION INSTRUCTIONS.
"Copy files from "2_new_files" to your Zen Cart install. If upgrading overwrite any existing files." I really don't understand what that means. If I install first time, Am I suppose to ingore "2_new_files"?
"A sample .htaccess file is included. Edit "3_htaccess/.htaccess" to match your web server's environment. Pay particular attention to the "RewriteBase" line. Make sure your server does not have "MultiViews" enabled (rare)." My web server is Just Host. How should I edit .hoaccess file?
I'm a rookie for help. Thanks

in a word, IF you feel you have to rewrite then: Ceon
