Things I need to know about the Unlocked IPhone 5, Verizon network?

So i'm Irish and and i'm going to New york on holiday in the next week. I've been planing on buying an Unlocked Iphone 5 while i'm there for use at home here in Ireland, only to learn that the Official unlocked IPhone 5 has yet to be released in the US

There's a very small chance that it will be released within the next two weeks so that seemingly rules out my chances of buying one. But today a friend had linked me with a site that claims that all IPhone 5's sold on the Verizon network in the US are unlocked phones.

On that point i know about apple's international warranty clause that basically annuls the warranty outside of the country which it was bought and i also know my country does not yet have 4G network.

But i was just wondering would the Verizon phone work properly back in Ireland and/or will sites like

Can I buy an unlocked iPhone 5 in the USA?

Can you buy an iPhone 5 outright (unlocked/no contract) in the USA yet? I can't seem to find any prices except pay monthly on, for example, verizon.
And if so, does it work out significantly cheaper than buying for £529 in the UK considering the 8% tax or whatever it is in the USA?

Can I keep my old number if I get an iPhone 5?

I have an old sim (2g apparently) and I want to transfer my number when I get the iPhone 5. I'm currently on o2 and would like to stay with them. Is it possible to swap my number or would it not work because its an old sim?

I think this should be such a simple thing but I've made it complicated and the o2 site isn't very helpful! I can't even order it off this site so have to get it from phones4u site but that only transfers numbers from different companies.
