Slack in the steering could be anything from the idler arm to ball joints, steering shaft bushing or steering gear. However, most of the slack is probably because of worn parts in the steering linkage (idler arm, tie rod ends, and center link). Those alone may rid of nearly all of the slack. I'd recommend replacing the idler arm, tie rod ends, and center link first. Then replace the lower/upper ball joints and wheel bearings/seals.
The wobble could be from bad tires, a bent wheel or maybe even a wheel bearing and a couple others parts depending on when the wobble is present.
