AutoCAD .NET :: Rotating UCS And Plan Command

I have two questions about UCS creation/rotation and the AutoCAD PLAN command:

Question 1) I am creating a new UCS, rotating it based on user picks and saving it.  The problem is that it saves the new UCS origin location, but it will not save the rotation.  The code I am using was pieced together from a couple of different sources (.NET developers guide and code from Tony T from an old thread)  How can I make the new UCS "save" the rotation as well?

Question 2) Once I have the new UCS created, I want to esentially use the AutoCAD PLAN command and rotate to the name of the new UCS that was just created.  I cannot find ANY info anywhere on the internet on how to replicate the PLAN command using .NET.  Here is the code I am using to create, rotate and save the UCS:

Dim acDoc As Document = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument Dim acCurDb As Database = acDoc.Database Dim acEd As Editor = acDoc.Editor Dim acEnt As Entity = Nothing Dim Zaxis As Vector3d Using acTrans As Transaction = acCurDb.TransactionManager.StartTransaction()Try ' Check for the exisitence of required blocks.
