Getting a discount from Currie is like winning the lottery, they're pretty firm in their prices. The Currie steering is the best hands down. Gerald at Savvy has the Currie Heavy Duty for $379 and the new macho Currie setup for $419 I think??? Give him call and insist on a JF discount
As to ball joints I would spend the money and get better quality, Spicer or Moog. A lot of people have had good luck with the NAPA Gold joints. I would get the best quality OEM style and forget the adjustable unless you have a big need for them. Spicer is usually the brand of choice.
On a side note, Jeff has a good quality ball joint tool but needs the Chrysler/Jeep adapters (about $40 or so), worth every penny.
Never heard anyone complain about the OME damper...
Axles are another story. I'm partial to Superior, I think their quality can't be beat, but plan on spending a paycheck or two. Something like the Super 30 with a locker will run $1200 and way way up. There's other kits from lesser mortals with 27 spline axles and a lockright for about half. Just depends on what you want to invest.
Keep in mind too that in strengthening Jeep components weak points get shifted. Stronger axles move weak points further down the driveline... Something to consider
And I would definitely go with the HP 30
