My 2 cents: a well built bar (one that exactly parallels the front edges of the lower control arms) makes the job so much easier!
A guy who owns a very large bending shop once showed me how he "adjusts" bends. The basic idea is that with a little persuasion, most any bend wants to straighten. Bang it hard in the "straighten" direction on a concrete slab and the bend will open a little. You might give this technique a try. (I've used it on 1" CrMo bars for Tigers and have been able to get the arms of the bar to fit perfectly along the front edges of the control arms.)
I install the bars with the front end weighted, as close to possible to ride height. However simply doing the work on the ground doesn't give much room to work underneath the control arms so I drive the car up on ramps. 6 inches is a good target.
I've used crummy V-blocks with a C-clamp to roughly position the end of the bar I'm not working on while I work on the opposite side. A jack stand in the center of the bar also helps.
good luck,
