How to find Schedule Performance Index (SPI) and Cost Performance Index (CPI) in Ms Project

I have an extensive experience in website development. I started with ASP Classic and almost spend 7 years in code development in ASP.NET. After quite some time, I plan to switch and with this intention I have recently passed my PMP Certification exam in my first attempt. I need to implement the following Cost Management formulas of Schedule Performance Index (SPI) and Cost Performance Index (CPI) in Ms Project. I have having trouble in it. Can you guide how it should be done, also I need to know where I should find the Critical Path of my draft schedule.

Any quick help will be highly appreciated.
