for some reason whenever I try to run sudo, and I enter my password, I get this result. "sh4d0w13 is not allowed to run sudo on localhost. This incident will be reported." I think this has to do witht he fact that I kept hitting enter the first time after typing sudo, and it said something about reporting me or something. But when I su and use visudo I wrote "sh4d0w13 ALL=(ALL) NOPASSWD: ALL". Any suggestions on helping me fix sudo would relaly be appreciated!

I believe that the line ought to be
sh4d0w13 ALL=(root) ALL

to allow you to run anything as root (with a tab in between your username and the first ALL, not spaces (can't type 'em here, it keeps tabbing between elements of the form >_<)).

Firstly, if this is your personal machine, there is no need for sudo.
You can su - to perform administrative tasks. The point of this, is so that you don't accidentally do something stupid (ask anyone who has used unix for a while - you'll get a story .

By using sudo, you are bypassing that restriction, allowing you do make a mistake when you are not root, and that is a bad idea.

Your visudo syntax is correct, however, I think you misunderstand how it works. Sudo by itself does nothing for you. If you wanted to configure an interface, for example, you would type:
The sudo command requires a command that you would like to run right afterward. It will parse /etc/sudoers, and make sure you have the permission to run that command.

Try it again - sudo init

You should get a usage prompt.
