The best place I've found for album art is Rate Your Music: http://rateyourmusic.com/

I was able to find a ton of stuff on there that no Amazon site had content for (and I searched all the Amazon sites).

On a Mac you can use Automator to batch resize a bunch of images - it will call into iPhoto to do it I believe. Or as mentioned, Photoshop's "Batch" tool is fairly simple when coupled with an action adjusting the Image Size.

I have a hard enough time adjusting "normal" tags that I think I'd go boonkers trying to put album art into all my tunes. I used the site above just to get images into my CD catalog and that was already quite tedious.

Any great tagger programs for the Mac? Has to be as good as Dr.Tag and Tag&Rename for Windows (I use both of those via VNC now).
