"Save As" dialog box in 2003/2007

[sam13484]

I need two answers and how they would apply to both Office 2003 and Office 2007. Please note that I have TweakUI installed, but I can't get it to do what I'd like:

1. How can I remove the default item on the left (My Network Places, My Documents etc)?

2. How can I make a desktop shortcut that will open the "Save As" or "Open" dialog box for Office 2003 and Office 2007?

Thanks!
