I'd be more concerned with ascertaining why the B&B floor is moving, It should be more-or-less completely stable. You can sometimes get minor wobbles when a bit of grit or similar has lodged benath one of the blocks, but other than that, there should be no movement. Sort that first!
The usual process then would be to lay a DPM, insulation (if necessary) then a screed of sand/cement, and finally the paving itself.
But all this depends on the B&B being stable. Any movement therein will only be transferred through to the eventual paving layer.
