using elements of atahualpa on custom (out of wordpress) pages

hello.

tried searching, but it doesn't come up.

i have a need to use the header and a footer on a custom page, and was wondering what elements/calls do i need to make to use the header and footer on these pages...

this is what i have figured out so far::

include '../wp-load.php';

include '../wordpress/wp-content/themes/atahualpa/header.php';

is there anything else i need to use to be able to use elements of the atahualpa theme on the custom pages?

thanks
