You will be able to download the instructions (PDF) and the partslist (XML) for the model.

One way is to buy them on Bricklink. You will need to upload the partslist to your Bricklink Wanted List and then Bricklink will automatically find the cheapest way for you to get all the bricks you need.

I ship all sticker orders within 5 working days if I'm not currently on vacation (see announcement bar at the top).
