-1 to the shrimp. It will get gross, nasty, and could introduce bacteria into your tank that you don't want in there.
I would just add some pellet fish food to get it going, and keep ghost feeding the tank throughout the cycle. Otherwise, you can add ammonia (don't remember how much per gallon).
I've read that urine (which is quite antiseptic for the most part) is a good way to get a tank going too. I haven't tried that approach.
