I don't know much about Rausch creek, but if y'all do get a chance to come to NC I don't think that URE will disappoint you.
As far as your upgrades go, steer clear of the revolver shackles unless it is a trailer queen. I had them on a Suzuki samurai some years back and they have horrible road manners. Try using FSJ(Wagoner,truck or full size Cherokee) front springs all the way around on the YJ. It will give roughly a 2" lift and will stretch your wheelbase a total of 4". This is due to the offset measurements of the springs. The spring pin is offset. I can give you some more details on this if it is something that you might be interested in. A longer wheelbase is most of the time better unless you ride on very tight and technical trails with marginal room for error.
