How can I delete/re-add music w/out losing the custom art?

Question

My problem is I have a huge music library. Greater than 160 gigs. So even the largest iPod, which I own, won't hold the entire thing.
I know that I can manually go through, prevent the iPod from syncing manually, and click which albums I want to sync and not sync. But in reality, it would take lots of clicking to go through and change up my collection entirely every so often. I mean it's possible, but I am looking for an easier way that won't lead me down the path of carpo-tunnel syndrom so quickly.
I am an ex-Zune user. What I used to do with the Zune software, is create 3-4 different folders, and seperate my music 3-4 different ways. Load up one folder, and when it was time for the next, I'd just delete the music entirely from the Zune software, and add the next folder to the library. Then when I connected the Zune, it'd sync, get rid of the original folder's music and load up the next. That way it's just a few clicks to change out hundreds of albums.
Will there be a way to achieve this with iTunes, but keep all the custom art? That will be hudreds & hundreds of CD's art that I will need to fix if I have to fix it every time I load one of the other folders.

If you paste in custom artwork it should be emdedded in the tags. Store downloaded art is only stored in the Album Artwork\Download folder.
I've written a script to create/update Folder.jpg album artwork in response to this thread - http://discussions.apple.com/message.jspa?messageID=12158746#12158746
I should be able to rework this script to embed artwork into any file that is missing it, but given it's nearly 4am here I'm going to get some shut eye just now.
BTW rather than moving stuff in & out of the library, move it in and out of playlists, then choose a selection of playlists that will fit on the device.
