Congratulations on your new toy!!!

Get a good precision screwdriver set. You can get good ones on Amazon for pretty cheap or there's a nice milwaukee one for like $35usd. You will need it. Also consider getting a couple replacement thermistors and heaters and lubricant and rubbing alcohol for cleaning all the parts, and as others mentioned, cheap glue sticks. Needle nose pliers and diagonal cutters are a must for the supports.
