Generally speaking, you want to take approximately the same amount of material off each side. The thought behind that is it will maintain the moisture equilibrium. In reality, you’re seldom able to do that due to imperfections in the material.

On furniture grade projects, I try to dimension the material in stages and let the material “settle” after each milling. This lets the internal tensions relax so you can get straight material.

Personally, I wouldn’t use a tablesaw to dimension the material. Since you have a planer and jointer, those are the tools of choice, especially the jointer. Use the jointer to “face” the material and then the planer to get close, say within 1/8", and then let the wood rest for a couple of days. You’ll have much more stable material.
