If I make the block smaller, ie. remove most of the excess copper and have channels to each area that needs cooling, will this help in the cooling effect? I guess what Im asking is, does more copper (not wetted) equal better cooling, or does the non-wetted copper actually retain heat? making the cooling water work harder?

From my understanding, excess copper is just that, excesss. Not needed.
It will retain heat upto the temperature of the surroundings (be that block, ambient air or water). The amount of heat is dependant on the specific heat of the material and the thermal resistance for it to be disipated through
minor heat paths (copper->air for example, in a waterblock).
Unless it affects the
major heat paths (cpu->water) it can not reduce cooling performance to remove or add it.
