When I did my suspension I didn't have any issues getting any bolts loose. If the bolts aren't rusty I wouldn't be worried about snapping them, just get as big a bar you need and give 'er. I used a medium power plug-in impact wrench and zipped them all off with no issues.
Ideally to time the bolts you'll do it on the alignment rack, by loosening all the bolts in question with the car on the rack, jouncing the car (or drive off and back on the rack very slowly), then tightening them back up. If you want to do this at home, you can do a decent job by jacking up the knuckle to the normal ride height and tightening down everything - this isn't ideal as you may not get the suspension to the exact ride height, but with some measurement you can get pretty close.
I believe factory ride height is ~660mm from the bottom of the wheel lip (not the ground) to the fender (maybe check this forum for typical ride heights, front and rear); from here measure the distance from wheel lip to center of wheel and subtract that from 660, then subtract for your springs. So, let's say from wheel lip to center is 254mm (20" x 25.4mm / 2) and your springs are a 1" drop (25.4mm), you get 660 - 254 - 25.4 = 380.6mm (distance from center of wheel to fender at factory ride height, minus advertised lowering), so jack up the knuckle until the center of the axle is ~380.6mm from the fender then tighten everything. It may not be exact but it'll get you close. Or just have the alignment tech do this while getting an alignment.
