Swedish currency and bank-connection

Hi everyone!

I just discovered OpenCart and I must say it looks superb! Nice, clean and powerful all together. I have a couple of newbie questions for you guys.
I was wondering if its possible to have Swedish Krona as the default currency? Do you think it's possible to connect the payments to the swedish banks?

Thank you in advance!

I've now managed to insert the swedish currency. All the articles are still counted in GBP even though I updated the local info under settings.

How do I fix this?
