I ended up doing this after creating that label:
Added this:
<TD align="right">
{include file="buttons/button.tpl" button_title=$lng.lbl_continue_shop style="button"}
</TD>
Right above this:
<TD align="right">
{include file="buttons/button.tpl" button_title=$lng.lbl_checkout style="button" href="cart.php?mode=checkout"}
</TD>
So it uses my button style and lines up right next to it. It also actually loads the front of the store again (my store is small). I wasn't sure I liked the Javascript thing. It works great.
