Answer 1

I believe you have to send the activity back to the performer not to the owner (which is "everyone" for the very first activity). You might have to change the following lines of code...

finishData.NextAssignee = new LinkToTrusteeData { 
        IdRef = processInstance.Activities[0].Performer.IdRef, 
        Title = processInstance.Activities[0].Performer.Title };
