can't find history information on a work item

Hi,
I have two simple questions.
How do I programmatically get history information on a Work Item?
And how can I programmatically change the status of a work item from e.g. new to defer?
I have searched in the code and in the forum to find the solution but without luck. I hope someone can help me.
Thanks
Martin
