The easiest way to handle these needs is to assign a custom variable to the product details page in admin. In your case you have a checkbox "this is a prescription product". If you uncheck it the prescription options go away.
In the case of your category "Help" the plan is to not have product pages, rather use categories and subcategories to display the content. If you need a specific product page template for your Help category, a new checkbox can easily be added to the product details page, and you can mark the product as help. Then we can take action in the templates based on this checkbox.
For example:
Code:
{if $product.help eq 'Y'}
{include file="customer/main/help.tpl}
{else}
{include file="customer/main/product.tpl}
{/if}
