All of the suspension arm bolts should only be tightened once the car is setting on the ground (or at least at normal ride height). If you tightened them when the car was up on jackstands, the suspension was fully extended. Once the car is lowered, the movement of the suspension will put some twist on the rubber bushings. That might be the source of your squeaking.
The camber arm bolts are about impossible to reach while the car is on the ground. So you need to get the suspension flexed to normal ride height while the car is up on jackstands. What I do is to put a jack under the suspension and lift up the suspension until the car just comes off the jackstand on that corner. Then tighten the bolts.
Another thing I always do is put anti-seize on the smooth area of the bolt and a bit of blue thread locker on the threads. I've had to cut too many bolts rusted into the bushing sleeve (frankly 1 is too many).
