Answer 2

• Turn of delete confirmation for Recycle Bin (Recycle Bin -> Properties -> Display delete confirmation dialog)
• Show Hidden Files and Folders (Explorer -> (Alt) Tools -> Folder Options -> View -> Show hidden files and folders
• Turn of Hide extensions for known file types while you're there.
• I turn off UAC, but I wouldn't recommend it for everyone
• Turn off Sidebar

Answer 3

IMO, switch off Aero. Both times I've had a new Vista machine I've gone around switching off the little pointless gimmick features before unearthing the master switch. Can't remember where it is.
