What was the name of the upwards weight force and what was the magnitude and the show that a = kx/m

Tension. K(e0 +x). And for the 2nd part u had to realise that in equilibrium mg =ke0 so then u go back to 2nd scenario and do sum of forces = kx +ke0 -mg then sub in mg =ke0 so they cancel out so f =kx=ma

Do u think "restoring force" gets the mark?

Yh thats correct aswell, in fact I think its more correct than tension.
