Laying Brick Effect

You can use a Gradient to control how shatter breaks up a layer. Once you get the layer to break apart the way you want, pre-compose everything or nest your shattered comp in a new comp and then time remap the nested comp to make the particles assemble themselves instead of break apart.

You will be much better off using Card Dance to build your wall of bricks. You have a lot more control over how things work. Divide the layer into rows and columns, then animate a gradient to make the pieces assemble themselves. No time remapping required and a lot more control. I didn't find a specific tutorial on laying bricks, but maybe this one will get you started. It's fair.
