find a free clan template, upload the files to your FTP, edit a bit of HTML here and there (links etc), edit a few image files (or alot) for new buttons, and also customising it for your clan (banners headers etc), and then when you are a bit more adventurous you could add in a game-monitor.com server status thing.

www.clantemplates.com is a good place to have a look at for a person in your situation as its quick and simple, but you might want to think of getting a better website when your clan develops.

For forums you might have to find a little help from someone with installing PHPBB or something free and similar, on your MYSQL or whatever.
