Mate, getting BF Goodrich combined with Ironman Foam Cell Pro is a complete off road setup. If your daily use was the opposite, 90% off road and 10% city, id say go for it but that's not the case. Basically Ironman has 3 categories:
Nitrogas shocks (Light-Medium off roading)
Foam Cells (Medium-Hard off roading)
Foam Cell Pro ( Hard-Hardcore off roading, Baja shit etc)
Id say go for the Nitrogas since you'll be using it in the city majority of the time. The new GR also has nitrogas shocks. These shocks are definitely better than the OEM ones in Fortuner Legender or Sigma. You'll have to get the springs too which I didn't because I had already bought new tyres, the springs increase the ride height by 2 inch and with that I believe we do have to change the tyre profile. The guys at Ironman said its not necessary to change the tyre profile because of the height increase but I don't know you'll have to research on this.
Coming to tyres, again AT's like BF Goodrich/Coopers with aggressive treds are mainly used for off roading and tougher conditions where the terrain is more technical and rough. In your case id say go for a mild AT tyre, Yokohama Geolander G015/Michilen LTX, these are AT tyres but not as aggressive as BF/Cooper, if you decide to get tyres with a more aggressive tred pattern I believe your ride will get a bit uncomfortable. People usually get HT tyres as well for better comfort but I think that just kills the benefit of having 4x4 vehicle.
