A compost heap built on soil will soon be full of all sorts of worms which will aid the breakdown of the vegetable matter. No need to purchase worms to add to a compost heap.
A worm bin (vermicomposting) is more complex, and whilst it produces useful wormcasts and liquid manure, and is a good way to deal with small amounts of household vegetable waste, it is not a practical way to deal with large bags of fallen leaves.
I bag up fallen leaves in bin bags which I then puncture and stack for 6 months. Then during the summer when we have lawn mowings to add to the compost heap I alternate the green clippings with a layer of semi-rotted leaves (good browns) which produces a right mix to produce good compost quickly.
You can of course keep the leaves in bags for 12+ months and they will then break down totally into leaf mould.
