Nevermind, called up a friend who's fantastic with Ubuntu, and he ran me through what to do. Used ndisgtk... i'll post steps below for anyone having a similar issue, even though it's probably already posted somewhere else:
1.) Open Terminal
2.) Enable the root account (may not be necessary for everyone, but was required for me. Apparently my computer's retarded or something). Do so by typing:
You'll be asked for the root password. If it's denied, put sudo in front of the command. It should work then.
nick@billy:~$ su root
3.) Enter the command line:
4.) Run ndisgtk either by going into "Applications > System > Windows Wireless Drivers" or by typing the following into Terminal:
root@billy:~$ sudo apt-get install ndisgtk
(Note: If you still have the root account enabled, you will not need to use the sudo command).
nick@billy:~$ sudo ndisgtk
5.) Click "+ Install New Driver"
6.) Locate the driver you have downloaded (if you haven't downloaded your driver yet, go to the company website of the card you're using, find the correct driver, and download the Windows XP version; save it to your desktop, and unzip it). Make sure that the file you select is a .inf file. Do not use the autorun.inf file that comes with most driver packages.
7.) It should install fairly quickly. Restart your computer, plug in your card, and configure it by right clicking the icon in the top right corner of your screen. The wireless connection you are trying to access should appear. Click on it. For some this is the last step.
8.) For others, you will be prompted to give a WEP Key (Verizon FIOs users, this is you. You can find this WEP Key on the side of your wireless router).
9.) Congrats, you should be connected.
Hope it helps those who have problems like I did.
