When I was just starting out I did not sell any international. After an Etsy friend from Canada contacted me about a book, I started selling there. If I were you I would not worry about selling international until you have more inventory and you have sold a few items in the states. Selling to Canada is very simple if you have direct checkout, you can print your label and customs form together right from your Etsy order. Also some international countries want you to list all of your personal information, like full name, address etc in your shop, so if you have any privacy concerns you need to keep that in mind. Also, read the forums about international shipping, there are some countries people just refuse to ship to because of the hassle. I have shipped once to Australia because the customer agreed to all my terms and the price etc. Personally I have shipped items to the UK and it seemed fairly easy, but I just haven't had that many people contact me requesting that I ship internationally.
