Dual front shocks? Depends on how hard you're going to be hitting a bump with the front end, or dropping it. All the shocks do is keep the suspension springs from bouncing the rig like a kid on a pogo stick. So while they look cool, unless you're going to be dropping it off of cliffs, or regularly hitting curbs at full speed, they're probably unneccessary, IMHO. But they look badass.
I wanted a lift on my rig strictly to get bigger tires underneath it, strictly to get the rear diff further off the ground to give me more clearance in snow, and moderately unkept logging roads. I'm not crawling with it, or jumping off stuff with it. That's what my K5 is for. Maybe if you figure out what you're going to be doing with it, it will help us budget your money for you better?
If your rig is not going to see regular trail use, I wouldn't bother doing the gears, but do the dual shocks. If your rig is going to see mostly trail use, I wouldn't bother with the dual shocks, but do the gears. There's also some tips on tires I can give you that will depend on your useage.
