Is it possible to edit/customise a New Item page, for a list
in Sharepoint 2003.

Examples of user;
I'd like to add a "Save and Close" button at the bottom of a Survey
I'd like to not show some unrequired fields on New Item Page for a task list
I'd like to redirect the page to different location when "Save and Close" is
ticked, not just goto Default View, maybe a Thank You Page

Is it possible

Thank you
