For the idea of doing the two sides in stages, if you are adding rock to a system that already has fish or coral in it I would use live rock. Before adding it to the tank I would let it cure in a seperate bin to make sure that you don't have any die off that could cause a cycle in the tank. If you use dry rock to add than you definitly would want to let it cure in a seperate bin. Again this is going based on adding rock to a system that has stuff in it.
