I am interested in using Zen Cart as a one page storefront featuring one e-book and three service options. Only one of the four choices may be purchased at a time. After submitting the order, the checkout and download process would go on.
Yes -
admin > config > Layout Settings > Main Page - Opens with Category > set cat#
Second, when editing the main stylesheet, will deletion of an item cause a breakdown of the system? e.g., I want to use my own main page in define_main_page.php but the system keeps adding a MainWrapper to it, in addition to the header and footer and graphics.
Actually can not do what I first stated and also have your define_main_page.php display
To adjust the removal of header & footer see tpl_main_page.php and the many comments
