Guest Checkout Shipping Zones

Hi,
I have several vendors who require their own shipping methods - at least 2 each. Some will have free local shipping and a fixed value for overseas. Others will have multiple rates for varying quantities. For the first option, I have set up 2 shipping methods - one for Australia ( country zone ) and one for Overseas ( new shipping zone all countries except Australia ). We have one vendor per cart and the shipping method is assigned to a vendor.

We use Guest Checkout only and the workflow is login, address on the first page, then cart, shipping and payment on the second page. Both shipping options show on checkout with the first in the list ( Free for Australia ) highlighted even when the address is overseas.

Also the URL for the second page of checkout shows ...../checkout/task-show/cid-2. Is this possible to show a more friendly url. I tried attaching the checkout to a hidden menu but that only showed home/checkout/checkout.

I notice that if you have only one shipping method and one payment method, they are still displayed as a radio button. Is this the normal display?

Regards
Linda
