I don't quite follow you here.
I see nothing wrong when I go to each product. The only issue I see if not misaligning images yet gradients which are in use in the indexhead template that are too small to use in our product.
The only problem I see on the page is that one area where "Welcome to the Bay Area Kiteboarding Reviews!" is at which is the index head template
You can get rid of the double gradient calls by editing your phpbb2.php file and changing this line
$Style['menubarnb'] = "cat";
$Style['menubarnb'] = "";
