Judging by strict thermodynamics, you'd want pump>block>rad>res. You want to flush the hot water from the block as fast as possible (high flow) and you want it to cool in the rad as long as possible(slow flow). The only wildcard is the pump. If you have a pump that creates a TON of heat, you may want to swap the pump and rad in order. If you're using a smaller pump, though, you definitely want it before the block.

edit: to answer your last question, with every turn in the system flow, your pressure will be reduced. That's why you want the pump before the block and not the rad, otherwise the rad will kill your flow before it gets to the block.
