The site that I used to purchase my camera was http://www.camcorderinfo.com/ . They have a page that shows their favorites at several price points, as well as in-depth reviews. A 3CCD camera similar to the one Scott recommended (the GS120) is their favorite under $800.

As far as computer recommendations, I'll stay out of the PC VS Mac holy wars. If you do choose a Mac desktop, I think the iMac is the sweet spot in the Apple non-portable lineup right now. The 2Ghz 17" or 20" would make for a really sweet editing station, and the included software (iMovie and iDVD) is really capable. We've had lots of fun with it.
