Hi Amy,
You'll want to do a check on the $main variable in skin1/customer/home_main.tpl
Code:
{elseif $main eq "resources"}
{include file="path_to/resources.tpl"}
{/if}
I'm not sure how your resources.php file looks now, but make sure you require auth.php, otherwise you may run into some errors if some requirements aren't being included.
