Does it affect the rate law whether the slow step or the fast step comes first?

The order of the steps does not affect the rate law, only whether the step is fast/slow.

I don't think the order matters, you just always use the reactants in slow step in your rate reaction

The rate law does not affect whether the slow step or the fast step comes first, but remember the slow step is the rate determining step of the entire equation.

Hope this helps!
