Please help with my 2010 Ram 2500 4x4 steering.

2010 Ram 2500 Cummins Crew Cab 4x4. The front tires were real bad and cupped too. Passengers side way worse than drivers side but both tires will need to be replaced.

I am going to replace what needs to be replaced but not sure what that is. The truck still drives fine on the highway except the passenger tire is loud and shaky now.
I see the boots on the tie rod ends are cracked so I'll replace those. The track bar seems tight when I pry on the ends with a bar. Should i replace it anyway? King pins appear tight as do the wheel bearings. I don't want to cheap out and wreck a new set of tires but I don't need to replace parts that are still good either. Anyone have experience with this?
