Yeah it looks like you're running out of shock length, and definitely correct your pinion angle.

As far as springs I would get the mono leafs and cal-tracs from Calvert racing. If you don't want to go with cal-tracs I would at least find a set of springs from a 340 car, worked fine for me into the mid 10s with a 9" tire. You can help them a little with extra clamps in front of the axle and removing all the clamps behind.
