I've not tried to hook up a monitor, keyboard, and mouse directly to the TP. I'm not sure how that would work.
As an alternative, have you tried My Mobiler? It connects (via USB ActiveSync) to your computer and allows you to see the phone screen on your monitor, and to use your keyboard, mouse, etc.
Go to:
http://www.mymobiler.com/release.aspx
for details, including FAQ and manuals. It's a free program, and I use it often to deal with things on my phone while I'm sitting at my desk.
Good luck!
