Question on functionality

Hello just a couple of quick questions.

I have 2 shipping regions: Europe and World. I am using normal geo ip location already so typically customers wont need to change shipping location.

I need shipping to be calulcated by weight for these 2 regions so it just calucates the total weight of all products in cart and grabs the price for the combined weight. I just wanted to check if this is possible?

Also do you have a premium version and what is the difference?

Thanks
