Bars and springs match?

I am gathering a list of parts in preparation of finishing my suspension.

Car is a 70 Dart Swinger 340 auto with sbp 14" Rallys. The front suspension has been rebuilt with a rubber master kit, using the offset moog bushings in the control arms. I am planning on purchasing the PST 1.03 bars and a set of ESPO 6 leaf springs +1" over stock. I will eventually add a 1 1/8 Helwig front sway bar.

What shocks should I go with? My thought was KYB'
Will the bars and springs be an OK match, spring rate wise?

The plan for the car is a solid streeter, not auto crossing, or drag racing. Just a comfortable ride, I don't care for soft suspension.
