Step by step on how to change the water pump and the starter..
The water pump is leaking fluid therefore I believe its time to change it.
The starter sounds like it doesn't engage the engine before the silenoid kicks out. Please what do I have on my hands as for as replacement is concern?

Typically you do need to shim the GM starters, usually a 0.025-0.030 shim will do fine. You may want to get a Haynes manual as well to guide you through this, as it's nice to have torque specifications for the water pump and starter bolts especially.
