It the water pump is bad there is a n easy way to check, normally the temperature rises gradually and if you pull the belt off and wiggle fan if there is any movement it's a sure sign the pump is worn out. also leaking out the lower weep hole is a sure indication the pump seal is gone.

Leaking water behind fan

The water pump is directly behind your fan clutch. Most probably, it's the pump. Shaft seal is already worn out (maybe because of damage bearing). You have to replace the whole assembly or replace the shaft, seal, and bearing. These items are within the repair kit that you can buy in parts store.

I dont know if the water **** is bad or if there are busted hoses, but I see water squirting out of a little L shaped hose and water runs out at the bottom. If I buy a new water pump what hoses do I buy as...

Water pumps usually have a weep hole on the bottom of the snout. This is put there so when the seals go bad you will know from the water leaking out. Try to look for that weep hole and see if coolant is coming from there before spending money on a pump. If the pump does not look as if it has been leaking then maybe its just the hose.
Not knowing what Pontiac car (or Truck) you are working on and what hose specificly. When asking for the hose at the store just tell them where it goes to. Water pump bypass, water pump to intake, water pump to heater core, etc..
