Do you determine the molecularity of a reaction by number of reactants? For example, if NO+NO yields N2O2 then it is bimolecular because there are two reactants?

You can determine the molecularity by looking at the number of molecules that participate/are used in the rate-determining step/rate law.

Yes you do.
A -> P unimolecular
A+B -> bimolecular
A+A -> bimolecular

You are correct that molecularity can be determined by the reactants, but we have to remember that this concept only relates to elementary reactions and doesn't apply to overall reactions.

Even though there are only NO molecules in the problem, using 2 of the NOs makes it bimolecular.

You can determine molecularity by the number of molecules of reactants.

Yeah, you calculate molecularity by the number of reactants in a reaction.
