It is really hard to give advice on a link set up, every rig is different. I built mine on the same chasis as you but I can gaurantee that my numbers will be different from yours in the end.
I also think that you can think this to death. Keep the links long, add as much separation as is practical, both vert and horizontal. overbuild. make it fit. That is my shade tree advice.
mine lowers are 40" my uppers 36" I triangulated both. I am at 108" wheelbase, but most of that is the front axle being pushed forward. I used 2" .250 DOM for the links. If I had to buy it again I would have gone bigger. I used 1x1.25 hiems (107,182 lb). I used a BTF truss in the rear and fabbed all my other brackets.
If you are in SLC and you want to come take a look you are welcome.

Last thing I will say is you can drop a lot of cash on links,SREs, inserts brackets etc.
