I'm pretty confident you won't need to do the body mount chop for 33" tires. I run 33/12.5/17 MTZ. No body mount chop, but lots of plastic trimming because I went 12.5" wide:bash:. I also welded some metal to the steering stops, and had to replace my UCA to some Light Racing UCA.
If you stick with the size that most upgrade to, 285/70/17 you do not need to upgrade the UCA unless you want, won't need to reduce the steering, and should have minimal trimming if any.
The most popular lifts are either a spacer lift, or ARB-OME shocks and coils. Spacers are useful for providing the space for 33" tires to give your truck an aggresive look. I offroad with several guys with spacer lifts on FJC's. It works well because the bigger tires is what gives you more clearance. The lift gives you space for the tires. I say OME because many many people use them, give the required lift, improve load capability are tried and tested around the world, and are a decent price. But overlandwarehouse stuff is suppossed to be top notch and they know 4runners and offroading.
Doing shocks and coils can augment your weigh carry ability and maintains your shocks ability to travel. This is the better option,but like I sais the spacers work to. With a shock/coil combination now not only can you fit bigger tires, which give you more clearance, but the shocks are longer, so they can drop down into a deeper hole and help to maintain traction.
I forget if you really need wheel spacers for 285/70/17. It's been awhile, and run different offset rims to run the 12.5" wide tires, of which again I forget the offsest.
But for for 35" tires you will need to do the body mount chop, and almost for sure you will need to do a 1.5" body lift, and plastic trimming.
Other things you might look into, regardless 33 or 35 tires. is the toytec 1/4" top plate spacer, diff drop kit, and sway bar relocate kit.
Also please consider some skid plates and rock sliders. Nice that you have a lift, and big tires, but rocks and tree stumps still won't be afraid to rip into the mechanics and underside of your truck.
And your sport edition will need to keep 17" or great rim size to be able to clear its larger brakes if you decide to change rims, or was thinking of getting a 16" rim size tire.
