I can't say I have that model of the F250 but I can say go with a quality set of leaf springs and shocks. Icon is as good as they come if you can get them for that year.
Also keep away from large heavy duty shocks, a smaller cylinder shock is going to be much faster in its stroke and slow for spring movement. ( you could pull all if your shocks off and take the truck for a drive xnd see if the stiffness goes away) of coarse you are going to have some major rebound going on but you can determine if your shocks are overwhelming your suspension. I myself am a Huge fan of adjustable shocks and the only ones I will ever use. I have Rancho RS9000 on truck now and really like them.
One other thing to look into is how do your rubber body mounts look?? If the cab has settled and sits lower than the bed on the body lines they're toast.
Last thing is going to be tire pressure, if you are running the max pressure you need to lower it. My tires for example are rated at 3,950 lbs load at 50 psi. I am at: 35 psi frt and 30 psi rr. Tire check with chalk is dead on rolling flat across entire tire. Of coarse this is a unloaded pressure and I bring it up when I pull the trailer or hauling weight.
Good Luck hope this helps you get started.
