Thanks to the both of you for your advice!
I ended up going with a kingston. The 512 MB SD card had a $15 rebate on it this month so I splurged and got that. I bought it from Zipzoomfly.com, as they had about the best price after the rebate according to pricegrabber.com, and were ranked very highly by users. Plus free 2-day shipping! Here's the link:

Arch13, I think some of that software is supposed to come bundled with it, but I'm not sure. I've got an an mp3 played so I'm not terribly worried about that, but if I would have anticipated buying this then I probably wouldn't have bought the mp3 player...oh well. Anyway, I'm writing down everything you reccommended and whatever doesn't come with it I'll look into getting.
Thanks again!
