That sounds fine to me. You could just lay the contents of the shipment on top of the bed in a pile and just leave them alone for a few hours and they should go into the bed fine. I like to leave a light on over any new additions for a day or so just in case they get homesick and start looking for their old bed. The newspaper sounds fine on top but I don't think I would wet it as those plastic worm houses have problems with excessive moisture already so I would put it in dry and see if it is moist at all after 24 hours. If not you might mist it a little bit.

Thanks wfike, it's good for the old confidence when someone else thinks it's a fair thing.

I'll try some dry shredded paper as you suggest, as the last lot of feed was greens (silverbeet) and it is a touch damp. I do keep a sheet of corrigated cardboard on top of the bed, just to soak up any excess moisture that may build up.
