Using GPO to make kiosk machine

hello all,

I am in trying to make few machine like kiosk with the help of GPO.  I created GPO called mykiosk and apply options in User setting. So far so good. But what I would like to do with these machines is :

1. Allow only Internet explorer
2. As soon as computer restarts I would like to Autologin with kisosk user account and start internet explorer.

Throw your ideas or point me in right direction. I seen Steadystate application from MS but since I have Active directory already in place it would be great to utilize the feature.

Thanks in Advance
