Rate-determining step

If the reaction is multi-step, I understand you include all reactants within the step and everything before it in the rate equation. When it says "everything before it", does that include the products?

For example:

A + B --> C + D (fast)
C + E --> F (fast)
F + B --> G (slow)

What would the rate equation be for this reaction? For example, would the 2 Cs and 2Fs cancel each other out?

And does anybody have an example of a question with a tri-step equation where the last one is the slowest

You ONLY consider the reactants of the slowest step.
