4'' Lift, Need Control Arms?

Hey guys, im sure this is probably and obvious answer to many of you. Im looking at doing a full suspension lift on my Taco, I have the 2" leveling spacers in the front already but i want to add the Old Man Emu 2in Heavy Load Suspension Lift Kit to it.

My first question is it okay to run the lift and the front spacers together? And will i need to get control arms to accommodate for the lift?

My second question is with the added 2" in the back what size tire can i run without having to cut in the front?

Im currently running 265-70-17s on my Gen2 Taco 4wd 4L V6

 

Magic 8 ball says yes.
