As for the transmission, you may find that it's the front pump seal that is leaking not the torque converter seal. I would change that, or at least have one ready. Could do the output shaft since you seem to be trying to fix all the seals. All the servos have seals as well, but if they don't leak now, I guess they will be good.

Seems to me if you are doing control arm bushings you are opening up the whole front end rebuild can of worms...ball joints? subframe bushings? Motor mounts?.....
