Dig it over, pull out the roots and dispose of them then cover the bed with manure, with the exception of any area where you intend to grow root veg such as carrots or parsnips. The worms and the winter weather will do the rest of the work for you and it should rake down easily in the spring ready to sow and plant your veg.
Far better to spend your money on manure than on topsoil.
If there are weeds coming through from next door dig out what you can then fix a vertical root-proof membrane along the boundary as described here
they suggest using damp proof membrane from builders' suppliers but specialist stuff is also available
