windows phone7 developer tools...where can we get them?

[pixelpower]

I like the windows phone7 disscusions but 1 thing is missing here. I need to know everything we have to download so we can develop and export windows phone 7 games and apps. I already know XNA,Silverlight,visaul studios express, but the more I read it seems like you need much more other stuff than that. What is it we exactly need , beside a windows phone7 emulator for windows. I want to start learning how to use new tools because I currently use Game Editor, but I dont think its compatible with windows phone7 so I got to start over from scratch. Any help and i hit thanks button.
I want to make games like you see in the photos. These are photos of a game I am working on for touchpro2. Thank you for your help
