Don't they both say that an object will remain at constant speed until an external force acts upon it?

Inertia is the inherent poperty of a body by which it neither changes nor tends to changes it present state of uniform motion or of rest.
This property is implied by newtons first law
Momentum of a body is the product of mass and velocity of the body.
This property is implied by newtons second law.
Thus only inertia implies that object will remain at constant speed until an external force acts upon it

No, inertia acts against momentum, specifically inertia is a bodies resistance to changes in momentum - i.e. the resistance of the body to a force applied to it that is trying to change its momentum.
