the top picture is of the sway bar, it helps with handling, keeping it tight in corners kinda. New rubber bushings will make it stop swaying (hence"sway bar lol) in corners. You can even get poly (hard rubber in different colors even), which will help alot. The tie rod is hard to tell in the picture, fill it with grease and see if it takes any slop out, even though it looks almost full to me.
the second picture is the bushing for the steering ram. If its bad, your ram will move and have sloopy steering and wear out the bracket eventually. Get a new bushing kit.
the 3rd picture looks like your idler arm, and its not rebuildable, and new ones arent that expensive, any doubts, replace it. If you can move it up and down, replace it.
If you replace the idler arm, and tie rods, get it aligned. the sway bar doesnt affect alignment, just sideways movement in corners

If you replace the steering ram bushing, alignment isnt neccecelery either. Suspension is fun stuff
