What am I doing wrong?

Where did you copy the files from for your custom template? Classic is the one
that's selected by default, until you set up your own custom template. It appears you've copied your stylesheet from the template_default (not listed in admin).

Second, I am having trouble editing the languages and css files. I've been trying to do this while in my cpanel. Does this not work?

No..you'll need to download a copy and edit with a text editor, and then re-upload to the proper
custom template folder.
