Disk Utility download

Hello again mac forums, I have a problem (surprise surprise)

Short version: I need a bootable copy of Disk Utility that I can burn to a CD and use. I'm away from home and unwisely didn't bring my OS dvds. I've searched high and low for a place to download it without luck. Where can I get this simple OS X tool to save my mac?


Long Version: My brother's iPod got corrupted. I tried to fix it. I plugged it in and used Onyx to view hidden files. My plan was to pull the music data off the iPod, restore it to factory settings, and then drag the music back on, hence avoiding any music loss. One problem I probably should have seen: Finder came across a corrupt file and promply froze. Restarting normally didn't work, with Finder frozen, so I held the power button. Upon rebooting, it just sat at the grey Apple, no loading bar appearing. I can get it to that firewire mode, but that can't help me.
Blessing and a curse: I have boot camp installed, which is a blessing because I still have some computer access to post this, but it's a curse because when I hold Shift to start the mac safe mode and scan, it detects a working Windows and a non-working Mac OS X, and ignores my Shift-holding, and boots directly to Windows.
What I think went wrong: When I turned hidden files on, it either made everything hidden or everything un-hidden, which one way or another prevents OS X from loading its own startup files.
Now I need Disk Utility (or so I believe) to repair permissions on my drive and get me back to my mac-filled bliss. Which brings me back to the main question: Where can I download it?


Whether you've read the short or the long, I hope you can point me in a good direction, or help me in some way. Waiting until this vacation is over is a very sad option and it would be infinitely better if I could solve this quickly.

Thanks
