Excellent point Jon.
You want your store to be setup the way you want it, but the only thing that makes money is moving goods, not a constantly updated web page.
Focus on security, useability and ease of layout at the beginning and then ride the site until you get lots of customer complaints like my pal John80y about your low quality pictures and descriptions.
Wait, John80y uses a bunch of my pictures and descriptions.
BURNED MYSELF!
