Fill the bed with a mixture of topsoil and well-rotted farmyard manure - you can get bags of both from the garden centre.
To grow the things I suggested there's no need to cover it at all. They're all fine outside in the winter.
You could also some some Aqualdulce Claudia broad beans in October - they will grow slowly through the winter and give you a much earlier crop than sowing in the spring.
And also Swiss chard can be sown now - you can use the small leaves as salad leaves in the autumn, leaving the plants to grow bigger through the winter and then you'll have lovely leaves and stems to cook in the spring - it would cost you a fortune at the greengrocers, if they even stock it. Such a lovely vegetable - use it like spinach, especially good in curries etc .
