You should be fine with the front shocks but you will need new rear ones and and I recommend getting diff drop also. 3" puts cvs at a harsh angle. I think you won't need a new panhard bar or drop bracket but I would do just to make it right the first time. I helped my buddy lift his 4runner thats how I know a little. Good luck with the lift.
