My husband just bought me that same machine. My new Bernina came with 6 classes on how to use it, clean it, etc. The manual is very helpful. I hope you love your Bernina as much as I do mine. Congrats!!
Also, look for sales on Bernina feet, that is when you will want to purchase your walking foot. They have many sales that you buy one foot at full price and get another half. This is how I have acquired my attachments.
