2009 Tucson Shock Replacement

I have a 2009 Tucson and I have reason to believe that at least a couple of the shocks are bad. I have purchased all four replacement shock assemblies. These are the full strut and spring assemblies and should be pretty easy to install.

However, I have watched some videos and the guy also replaced sway bar links (indeed even ended up breaking one of the originals in removing it) and recommended replacing the bottom bolts for the shocks as well.

Is replacing the sway bar links and bolts actually necessary, provided you don't break anything and they come out undamaged? Should I have buy replacement sway bar links and bolts?

I will edit this later to add links to the videos in question when I get a chance.
