Kernel Panics! (I'm pretty sure I know the cause- but how do I fix it?)

Question

Okay, so I installed a program called fkeys that changed my caps lock into some other key (supposed to be control, but seemed more like it was option). Eventually, though, I discovered that the caps lock key is not as useless as I thought, especially when I want to express extreme emotion while chatting.
So I tried to uninstall it. Apparently fkeys is a kernel extension (that came with many warnings before installation) that doesn't have an uninstaller. Well, I read the warnings, but uninstalling looked simple enough.
There is unfortunately no automagic uninstaller for fKeys yet. To uninstall fKeys, execute the following in an Xterm or Terminal window:
sudo kextunload -b com.kodachi.driver.fKeys
sudo rm -rf /System/Library/Extensions/fKeys.kext
sudo rm -f /System/Library/Extensions.kextcache
sudo kextcache -k /System/Library/Extensions
sudo rm -rf /Library/Receipts/fKeys.pkg
I mean, just cut and paste right? Well, what ends up happening is that the first command asks for my password. I do that, continue on with the next ones. Oddly enough, the next ones don't get me any response from terminal. So I try them a few more times (entering those commands in terminal). The second or so time that first command results in terminal telling me the driver can't be found.
Then I decide to try reinstalling it because it didn't seem like I uninstalled everything. So I try that, but the install doesn't work. I tried the other version... the install dmg doesn't even mount. So I decide to restart... and boom, kernel panic. (Unfortunately, I have experience with kernel panics from ram problems).
Soo...
-It says that it's "unable to find drivers for this platform: powerbook: 5,6"
-I have a 1.67ghz Powerbook G4, w/latest updates and stuff.
-Safe mode does not work
-I'm pretty sure this falls under "6.1. Assure drivers and kernel extensions for third-party hardware are current" from the xlab faq as this occurred from me trying to uninstall a kernel extension.
I don't have my install discs with me. When I get them, I'm planning to boot off of them... but what do I do from there?
Would I be able to uninstall the kernel extension? Or do I have to resort to a archive/install? Would that even fix it? Am I going to lose all my data? x_x
Thanks in advance!
edit- My friend tells me it's possible to boot off the disc and then access the hard drive and then move the data I want to an external hd... is that an option too? How would I do that? Once again, thanks a lot.

Hi Eliott,
I'm surprised no one has tackled your problem. Maybe this will bump it to where someone more knowledgeable will see it. Anyway, I'd guess that the reason the Terminal commands after the first one "got no response" is that once you authenticate sudo, you're good for a limited time, so the rest of those lines ran without needing further authentication. But I don't know enough about those commands to know just what got hosed. Maybe someone who does could prescribe the correct micro-surgery.
When you get your disks, you could try booting to the disk (hold C key at the chime), and run Repair Disk from Utilities in the menus at upper left (don't go into the Installer). You want to get two consecutive "HD appears to be OK" reports. If that doesn't work, you are probably in for an Archive & Install. You shouldn't lose your data but it's best to be backed up. Similar to what your friend suggested, you could try connecting by FireWire to another Mac and booting into FireWire Target Disk Mode to pull your data off the disk before re-installing. I hope this is some small help-- good luck!
