I have a Huawei Android 4.0.4 phone and I've recently downloaded a Terminal Emulator app. This app allows me to run a Linux shell from inside Android; it runs /system/bin/sh. I started to navigate around the OS and I've found that /system/xbin only has DisableLoopTest, EnableLoopTest, dexdump, and hciutils_test in it. /system/bin has many files; I believe that all of the installed commands are in it. However, I noticed that su and sudo where not in /system/bin or /system/xbin. Where can I download this file or some other file to root my Android device?

    You need to search for a specific guide to root your device, just adding the binaries won't help (you can't add them anyways, because /system is write protected).

As it was correctly stated by the GiantTree, adding su binaries won't help you much as you do not have root. After rooting they more than likely will be added by default.

What concerns adding missing commands to Andorid shell, then you'd better not to do that one by one, bur rather install Busybox. It contains a big set of predefined commands.
