You could just go to Network and Sharing Center and go to properties of your current connection, then double click TCP/IPv4 and check your IP address from there. That's a better place to check your PC's IP address in my opinion.
You could wait for a sale, but there is a risk it still wouldn't reach you alternatively you could buy something digital (like itunes cards) and try to recoup as much as you can. I really don't what to say man sucks that you had such a bad experience with :/
Moving permanently to Lahore and like no one is going to be at your current residence to receive?
I don't think there is anything you can do, since they ask for you to wait at least 6 weeks. I wouldn't worry about it just yet - worst case scenario: you don't receive your item and they give you full refund as store credit.
The account thing Idk, if you have a Visa or MasterCard it should work, as for the currency conversion charges you should ask your bank about that.
Weight and the declared value factor. If its just a standard $60 game (and you don't choose one of the courier options) then yes you should not have to play any tax/handling charges whatsoever and it will come to your door step... eventually.
If you are not in a rush and whatever you plan on ordring amounts to $60 or more, I'd advise you to keep an eye on their Facebook page, people post '$5 off $60' coupon codes there.
If your package gets lost they'll reimburse you with store credit regardless of if you chose to spend the extra 4 bucks or not. Its just an add insurance really, I usually opt out.
The only thing that I'll stress upon is go for the box instead the envelope.
