Suspension & Shocks: doing maintenance & upgrades. Suggestions?

Well as for shocks on the TV I would replace with Bilstein’s, yes the old ones are likely still working somewhat but Bil’s will dampen far better. I had a 2001 Ram 2500 and replaced the shocks at 255,000 miles. They were still charged but the Bil’s I put on did a much better job, stopped the bounce with 5er on first cycle not third. They were the original factory shocks made in 1999!
