I've read a lot of conflicting information on vermiculture. I'me sure everyone's experiences are different and may or may not be applicable for every instance. I've been following the info I mentioned above, available here as a .pdf file:

It seems well written and verified. We have lots of night crawlers living beneath our compost bin. They usually find their way into the composted material but only at the lower levels. I've never tried burying kitchen scraps but I would guess that worms would find their way to it. We try to do our part toward keeping our waste stream to a minimum by composting and recycling.
I'd like to see your leaf mold pictures. Good for you for using an available resource.
