The only risk you run with the approach you mention is if those pages are currently pulling in any traffic with the SEs. If they aren't, I would go ahead and change them. If you do, I would go ahead and keep them live for a couple of months, just in case Google got them (you can always put up a redirect to the new page also). You may want to consider making a sub directory 'bar_mitzvah' and then pages with extensions like djs.html and so forth. For a great strategy on how to structure your site, I would take a look through this thread [webmasterworld.com...] . Also, link all your pages using text links with keywords in them. Give good content on each page mixing in keywords and you are on your way.
