I used the same type of windows on an old project. I know it is late in the game in your project with the spray insulation, but I framed between the inner and outer walls with wood all the way around so it would be solid when the window clamped in and the walls could not squeeze together and make the window loose. As far as the mismatch in thickness, my windows were surplus and I had the same issue. Just get a sheet of 1/8" thick whatever you can find and cut out a nice ring the same size as the window frame for a shim.
