Hi,
1. You'll just have to move the "terms and conditions" through your checkout workflow ("Hikahsop->System->Configuration->Checkout").
2. Sure you'll just have to edit the "Term" file of your "checkout" view of your front-end template through "Hikashop->Display->View" and change this line :
<input class="hikashop_checkout_terms_checkbox" id="hikashop_checkout_terms_checkbox" type="checkbox" name="hikashop_checkout_terms" value="1" <?php echo $this->terms_checked; ?> />

<input class="hikashop_checkout_terms_checkbox" id="hikashop_checkout_terms_checkbox" type="checkbox" name="hikashop_checkout_terms" value="1" <?php echo $this->terms_checked; ?> checked />
