I agree with most of the comments above. I would suggest that you use Klarna since you can offer invoice to your customers. SSL is a must for a shop in Sweden and i personally would not feel comfortable shopping online without it.

When you reach the "beställning" part you give contradicting information. On the top of the page it says 28 days to send the product back but in the but in the form you give the information that its 14 days. The site window has a danish name instead of Swedish.
In the "leverans" part you have "Brug en anden faktureringsadresse" which is Danish and not Swedish.

So to give my conclusion:
Translate everything properly.
Use SSL and as someone said above shorten down the way to actually pay for the stuff.
At least put step 1 and 2 on the same page.
Get a Swedish nr for customer service.
Get Klarna or another payment provider since that would increase the trust in the site.
