Here is a sample code to get the groups in Silverlight app by calling the GetGroupCollectionFromUserAsync method of UserGroup.asmx web service.

Why don't you explore possibilities of SharePoint Web services? I think you can reach your goal much easier by using web services then by using Client Object Model.

Take a look at UserGroup Web Service and its method UserGroup.GetRoleCollectionFromUser Method. I believe this method to be exactly what are you looking for.
