A lot depends on the version of Windows that you're running on. If Win9x, you can disable the Ctrl-Alt-Del secure attention sequence fairly easily via some API calls (do a search in the VB6 forum, it's been covered there alot).
If on WinNT, Win2K, WinXP, Win2K03, you'll need to fire up Visual C/C++ and write a Win32 DLL called a GINA dll, which acts as a authentication filter. A simple keyboard hook will not do it, as that key sequence never shows up in the hook methods.
Don't know about hiding control panel, etc.
Microsoft used to sell a version of Windows that could be customized by an OEM, and is designed for use in a kiosk environment. Take a look at the hardware OEM part of their site.
