Thanks, na.1788! I deleted all the lessons thinking I needed to start over, download just the elementary level, tag it in some way; then create another playlist or group or something to do only the intermediate. Of course when I did that, popupchinese for some reason downloaded them all again even though I had changed my subscriptions to elementary only. No idea why it did that, but itunes is now merrily downloading all and sorting as it goes... A mere 1039 items. No idea how I'll decide which ones to concentrate on.
