Rob:
You can indeed copyright your website and all contents, and I strongly recommend that you put copyright notices on all pages. You don't have to actually register the copyright in order for it to be effective, but if you're going to pursue legal action, you might have to.
However, that alone will not protect you, as our company has all too much reason to know. In the past month we've found no less than 3 websites that have pirated our copyrighted work, in one case taking 4 of 7 pages and reprinting them word for word. One of these sites is actually perpetrating a scam, which makes it worse still. We got 2 of the sites shut down by complaining to their hosting company, and are working hard on the 3rd one.
Your first step is to contact the people who have stolen your material and inform them that it is copyrighted, they are in violation, and you are aware of that fact and will pursue action against them if necessary. If they have live websites, you also need to contact the hosting company for the websites and let them know. A reputable hosting company will shut the site down immediately. eBay also has some helpful information about pursuing copyright violators (

Good luck!
