The Hotchkis rear coils are pretty firm, I'm currently running them on my truck but they are 6" drop, so that probably doesn't help you. Hotchkis included spring plates to adjust the ride height a little bit though. They don't beat you to death on the highway, but they definitely feel firmer than stock springs I had before lowering the truck. They are rated at 380#/in. I'm running Chassisworks DA Vari-shocks on damn near full soft too. I have never tried CPP's rear springs, so I don't know how they'd compare with the Hotchkis springs. I will say I've never experienced any wheel hop at all with the Hotchkis springs, but I don't know if I have what you'd consider 'extra power' - I may not even have enough torque to twist things up out back.

On a side note, GMC Pauls offers drop springs that they can get different springs rates on. If you know what rate you want, you could also get some custom springs wound too.

As for the panhard rod, I don't know that either, I'm running the CPP deluxe bar with the Moser Engineering version of the T/A cover you speak of. Everything clears just fine.
