Configuring a Server

Hi, I just moved my website from a shared hosting environment to a dedicated server on [login to view URL], and the server is setup and running but there are still a few configuration problems which need clearing up. (Warning, my site is a hentai site, i.e., it has adult content.) If you can't / don't want to do all of the following, that's fine, let me know what you can do. I'd like the following done: -phpgraphy (a php-based gallery program) used to work fine, but on my new dedicated server it won't display galleries properly anymore. I'm guessing it's an authorization problem--the pictures and folders return a 401 page from the browser. -Prevent image hotlinking. -Prevent directory listing (Forbidden error if there's no index) -Setup FTP backup (I bought an FTP server which can be used) -Generally make sure that my server is configured correctly so that it doesn't run slow, isn't insecure, etc. Right now my server is running very slow probably due to phpgraphy messing up. This is all simple enough stuff, but I'm not competant enough to do it myself. My server is running Fedora, with GoDaddy's proprietary control panel installed (no cpanel or Plesk). I can give you SSH root access, FTP access, and access to this control panel. Thanks guys, good luck bidding!
