On the blocks used for our landscaping, they dug down a little and placed sand under where the blocks were to be placed. The blocks are pretty heavy so I don't think they will shift much. For the caps they used a caulking gun to place a line of glue between the cap and the block which effectively gave even more solid weight to the top layer. There are two layers of block and one cap. I can't speak of longevity since the walls were just built!
