I have an 89 wrangler with Dana 60s and 39.5 Irocks and I am putting a triangulated 4 link in the rear. I have gathered all the pieces and done the math, but I still don’t know what rear coil springs I want. I will be running a full size spare, and tools, 15 gallon fuel tank, and my 3 year old daughter in the back.
I was thinking TJ coils, or XJ coils or possibly F150 coils, any thoughts on this..or any one running these coils?

TJ and XJ coils are interchangable size wise. The XJ will give a bit more height for the same advertised lift. They are very similar, if not the same, rate depending on manufacturer. I would give them a try. You already have a good idea how the coil rate works, just decide on the height and you are done.
