Frozen dumplings in bulk from Dumpling House in Temple City
In case anyone is interested, you can order frozen dumplings from Dumpling House in Temple City. You need to order at least 50 dumplings. The cash price is 20% of the regular price, so it'll be about $23 for fish dumplings and $19 for boiled-type pork dumplings. You need to order in advance (one week for us). The good thing about this is that you can specialize your order. For example, we ordered dumplings without MSG and half the salt they would normally use.
The owner recommended boiling the dumplings. Customers have complained in the past that the steamed dumplings fell apart. He's not sure why, though, but there have been no problems with the boiled dumplings. Here's the contact info:

The best frozen dumplings I've had are from Mama's Kitchen on New Avenue just south of Valley. They have very good frozen XLB - just put them in the steamer frozen and steam them for 12 minutes. They're not as good as fresh - obviously - but I've never had better frozen. And they've always got them, you don't need to order them in advance. Bags of 50 seem to vary in price - according to mood, who knows? - from $15-20.
Strangely, the fresh dumplings aren't as good as they are at J&J or Mei Long Village, at least not the XLB. The pan fried dumplings are pretty good. I've never had any trouble ordering and I don't speak Mandarin - just grin and point at the menu. The frozen dumplings are in a case by the cash register and I just point to the bag I want.
