Using Paypal

Description

Hi
I am based in Ireland but sell alot to the the UK. My paypal account was setup with a euro card. I just want to the know the following:
1) Can I receive payments in sterling? if I was to attach this account to an UK ecommerce will my customers know that this is a euro account?
2) I see I can have different currency wallets on paypal – can I also attach bank accounts to this paypal account that are also different currencies?
3) will I have the option to transfer UK £ into my UK account with out FX fees?
