the general consensus around here is that, the new crossmember and arms don't make that much of a diffreence compared to simply crankin the t-bars and gettin an alignment, most people also agree that the calmini shocks aren't up to par w/ their expectations, the front really doesn't require any purchases other than maybe snubbers, and the recommended manual hubs, which i think i remeber readin you already have, the back well you have lot's of options cause of your leaf spring set up, and to top it off purchase the shocks of your choice, i'd do a search on the shocks, based on your preference it'll be better than askin now, it's been discussed ad nauseum
i can vouch for matt that, when youd deal with him you get good friendly service and he'll tell you the truth, i'd reccomend matt mainly because he's great to deal with, most people also say the same of joe @ www.darlington-offroad.com but also do a search on calmini and you may find some discouraging news, compared to the reviews of matt and joe
good luck!
