Thanks Seth. Reading around a little more it seems for a street vehicle I should shooting for 50-55% AS.
Using the Excel version of the suspension calculator that Chad linked (thanks Chad) I have started tweaking but right now I have a RCH of 12" which is just above the bottom of the pumkin and below the pinion snout.
I can get it lower but to do so I have to drop the lower bars and I start to worry about how long the mounting tabs on the bottom of the housing are. Is 4-5" too long?
BTW the dynamic #s in the Excel calculator show the pinion angle changing by about 0.3 degrees per inch of bump so at the full 5" dump there will only be 1.4 degrees of change.

Edit - one other thing: how much change in the RCH and AS numbers should I be aiming for?
