Can someone help me with my cockatiel question?

I’m going to be a first time bird owner soon. I have already done a lot of research, but was wondering if there was anything very important I needed to know. This is the cage I will be getting fro my two cockatiels http://www.kingscages.com/ProductDetails.aspx?ProductID=ELT_101
What kind of toys do I need for my cockatiels? OH! And what type of food should I buy for them?
- Cockatiels ROCK!!!
