I realize this is an old post, but I thought I would share the answer to the question if someone else should ever need to no.
Contact the Albanian Embassy or Consulate in your Country, they are extremely helpful and will tell you what documents you need, and how to get them. You can google the contact information for the Albanian Consualte or Embassy in your Country.

These were the requirements as of May 2010:
1.)Your long form birth certificate, showing your parents names, birthdays, and birthplace. This needs to be authenticated in your Country.
2.)A statutory declaration saying who it is that you are marrying, your citizenship, that you have never been married before or are legally divorced.
3.)Everything needs to be translated into Albanian at the Embassy in your Country and also legalized at the Albanian Embassy or consulate in your Country.

You have to be in Albania for 9 business days before you are able to be married, which makes it tricky since the above documents expire after 90 days. I am Canadian.
