status of started service and starting service

Add a reference to System.ServiceProcess to your project and then you can get information using the ServiceController class, like this:

ServiceController controller = new ServiceController();
controller.MachineName = ".";
controller.ServiceName = "Tomcat6";
Console.WriteLine("Status              {0}", controller.Status);
Console.WriteLine("CanPauseAndContinue {0}", controller.CanPauseAndContinue);
Console.WriteLine("CanShutdown         {0}", controller.CanShutdown);
Console.WriteLine("CanStop             {0}", controller.CanStop);
Console.WriteLine("DisplayName         {0}", controller.DisplayName);
Console.WriteLine("ServiceType         {0}", controller.ServiceType);

The class also has methods for starting and stopping the service.
Note that you have to pass the name, not the display name, to the Name property, you can get this by right-clicking your service and select Properties.

Hope this helps,
