A few linux questions
 

How do I configure so that only root and my main user can create AT jobs?


How do i set a bootloader password with timeout value and change the display name?

For permissions issue, you can look into sudo. For configuring the boot loader, you will need to edit the config file for the loader. If its grub you can configure it using grub.conf or menu.lst depending on the version of the grub and the distribution you are using.
Also please from next time use better titles to suit your questions. http://www.catb.org/~esr/faqs/smart-questions.html . A recommended link for reading.

Any more info on the sudo? I'm lost

All info is right here. Good luck!

(Next time show us a bit of what you are doing exactly and what you want to do exactly. That makes answering you more accurate and helpful.)
