How do I assign an armature to an object?

Yes a noob question. I just can’t seem to find the “assign” button anywhere.

Did I order my objects and armatures wrong or something?

Select your object, then your Armature. Press Ctrl + P to Parent, choose “Automatic Weights”.

Or, select your object, add an Armature modifier. The first way is generally better though

Depending on how your mesh is set up, the bones in the armature will affect it differently. Automatic Weights try to do their best, but a lot of the time, you need to do Manual Weight Painting to get the desired result
