1) The only thing that you aren't given access to with Telerik's RadControls for Windows Phone 8 trial is publishing apps to the Windows Phone store. You will need a license to use the RadControls in a published app.
2) You can access the Telerik template pages by going to the menu bar at the top of visual studio 2012 -> Telerik > Rad Controls for WindowsPhone > Add RadControls Item. From here you can see dozens of templates to use in your applications.
Hopefully this helps,
