Way to go!
Indeed an eye-catcher once done. I'm assuming a detailed homework must have already been done before undertaking these mods.
As @raohamid mentioned about gear lever, in addition steering shaft extension, radiator lowering and some other minor but important things like extension of flexible lines will also be required.
In my humble opinion, 3" body lift would be sufficient to proportionally accommodate 35 - 37" tires without asking for much more modifications and will look aesthetically good without compromising road handling characteristics. Vigo already has big wheel arches and is modestly lifted.
Again, assuming you must have gone thru all this stuff many times over, just for reference for the readers, here is what it will hopefully look like when done as per the given specs.
Toyota < Brands < Arctic Trucks
Wish you all the best of luck.
