there are a few things you neeed to remove: fan shroud, then the fan, then the belt, and you need to unbolt the p/s and a/c bracket, dont take any lines off, just pull them to the side out of the way.
after you get the water pump off and get ALL the gasket material off then you can start putting it back together.
if i were you i would go to NAPA and buy a new water pump and a can of "indian head shellac" and cover both sides of the gasket with the befor you put it on. you may want to get some new bolts when you put it back on, instead of taking a risk of breaking one off in the engine.
after the pump is back on you may want to hood the rad. hoses back up befor you put the fan and the rest of the brackets back on, and put some antifreeze in it just to make sure its not leaking. befor you get it all back together and realize you gotta take it all back apart, lol
