What you are probably having the biggest difficulty with is getting past the water pump pulley. It is probably spinning when you try to loosen the four bolts holding it on. There is a special tool to hold the pulley WITHOUT damaging it or anything else. Go back to the parts store that you bought the pump from. Many of them will lend you special tools needed for the job. The NAPA in Buford probably has the tool, though I don't know specifically. The tool is called J 41240. You can google it.
After that, its pretty straightforward. You need the tool to reinstall also.
