Some feedback on the website...
If you are looking to use the website as a marketing channel to obtain new students (which you should, search engines can drive some greate customers your way), then you need to look at something called search engine optimization. There is a great book out there, Search Engine Optimization for Dummies (don't let the name fool you, so great info).
To start, your pages are missing somthing called page title tags, Right now your Hompage is called "Home". This title is diplayed to the user by their browser, but mor importantly it tells the search engine waht the page is. Get the full name of the school/club and get the style in there too. For all the other pages, use the name and then the name of the page. Do not just say newsletter or photo gallery, call it Martial Arts Newsletter or TKD Photos.
Next, I know you wanted to keep updates to a minimum, but at least update the newsletter page once a month and try to make updates to other pages at least once a 1/4. Search engines like fresh pages. When they do not see any changes, they assume the page is dead.
For your homepage, try to write a descriptive paragragh that uses words associated with the school, style, instructors, etc. Think of words you think people may search for on the web.
Last but not least... pretty website does not equal results. I have created a very simple website for our school and one of our clubs. I purposely kept the site clean, simple and most importantly - search engine friendly.

I hope this info helps some other school owners. We are getting a high percentage of new students from the web.
