First I have to say - Youngy, your setup sounds thus far the proper way of doing things. Good job!
I myself will not stretch as far as having multiple hole brackets. I shall most likely just restore attitudes close to factory angles and leave it at that.

I have found some material in the net that supports my view on the pinion angle issue. (What it's worth, I gather almost anyhting can be proven if we hold 'stuff found in the net' as absolute truth on the matter.)
After ploughing quite a bit in American drag racing forum world, these two quotes sum up well info I've gathered on this pinion angle (PA) issue. I found these at: http://www.hardcore50.com/

Dan at Wolfe Racecraft told me last week that he doesn't know why people are so anal about pinion angle. He said their cars go the same no matter what pinion angle they use. I have to agree with that. I've tried anywhere from -5 to +2 and 60ft'd the same. What I did notice was that anything positive produced drivetrain vibration.

In my testing, what NoSlix said that Wolfe told him is true. The only thing you are trying to do is reduce friction in the driveline, it will not affect traction or the car going left or right. Yes, the reason you adjust the pinion angle down is because of upward pinion movement under accel. As for your comment on the ladder bar/4 link advantage, PA will still change as the suspension travels but because the ladder bar/4 link has solid mounts it won't deflect. With rubber bushings they have to deflect or the suspension will just bind up. One last thing, another place that you can measure engine/trans angle is the starter, it's bigger than the damper and easier to stick an angle finder on, unless your headers are in the way which is highly possible.
