Samsung Captivate :: Superuser Permission / How To Uninstall / Delete Forever?

So for the past year I have been using a blackberry bold 9700. At the time when I bought the phone, AT&T didn't have any really appealing android offers. Anyway, the captivate came out, and it seemed like finally there was a good, high end android phone for my carrier, despite AT&T's usual bloatware BS. So I went onto craigslist and found some dude who was willing to sell his captivate for 200 bucks + my bold 9700 (side question, was that an OK deal? I feel like a little less money would have been fair).So we met traded, I'm finally on android, I love the phone, but there is one problem.There is an application on the phone called superuser permissions that I can't delete.I found out it's a program used for rooting.Even though I plan to root my phone eventually, I don't want to root it yet (I'll wait until froyo is released for my phone), and I would rather just root it myself and know what I did to my phone, if that makes any sense.

To make matters a little trickier, I use a mac. I can transfer files between my phone and my computer by going into usb debugging, but the samsung only has drivers that work with Windows... I don't know if that's a problem or not but I just thought I'd mention it.
