Regarding the lower control arms, I would probably suggest replacing the bushing at the front of the arm, as you can manuever it into the press easily. Think carefully about trying the rear mount's bushing. There is no easy way. There's little clearance and you'll spend a lot of time on it, plus it's very robust so I would tend to think it could be left alone. But, then again, I was able to do it in my driveway...
