What does your alignment shop say? Are parts "worn" out or are they still good?
If they are still good, they may still fail somewhat premature due to the added stress of the larger tires, but that can happen even with newer parts.
Again, if they are still good, but then fail, would you still have the funds to do a repair/replacement if the need comes up? If not, you may want to wait before upsizing and adding the additional wear potential to your rig. This would apply to what is on your TB now or if you replace everything first then add the larger tires.
I only ask as everyone has had different experiences. Some have lifted and not had to replace many parts if any at all, while others have lifted and have had a never ending replacement issue. I would think a majority fall somewhere in between.
Myself, since adding the lift at about 60K and then 35's at 90k, I have replaced one half shaft and bent lower rear control arm. I now have 133k mi, have been to the Dakota Territory Challenge 3 times, Moab twice and other smaller runs and outings between.
So sometimes you get lucky, other times you pay. As long as you pay attention when things sound different or feel different and do an inspection on your rig at least a couple times a year, more if you off road more often, then you should be fine as long as your current parts are not worn.
