Unfortunately, we do not have samples yet. In general, you should not work with Nolics classes directly regardless whether your data access is using Nolics or something else. Instead, you should use the API and interfaces. This way you will keep your code independent of system and module data providers.
There are several approaches to support localization. If you give us a scenario, we will suggest the best approach and give you an example.
Could you also elaborate how do you intend to use Workflow? If you want to hookup to events, I will show you how you can do this in v3.1, note events are not exposed in v3.0.
If you want to create workflow for your own objects, I would suggest you start using Windows Workflow Foundation as we are going to migrate to WWF with v3.2.
All the best,
the Telerik team
