Welcome aboard to the site....Here is what i have found and other's i'm sure will chime in and agree...
Personally I make sure everything is mechanically sound, No leaks, everything feel tight? Engine run stong, need more horsies, maybe try a upgrade to the ignition system and a edelbrock performer intake. Starts everytime...etc etc.... In MY opinion any problems not addressed before lifting, and other non-neccesitative upgrade will just kick you in the butt before you know it.
From there,locker, winch, custom bumpers, etc etc....lift and tires will get you places but 32-33 range you can get through most moderate stuff, I wheeled mine hard for 2 years on 31's got a feel for the game and upgraded from there.
As mentioned once you have your drivetrain engine and main steering braking stuff straight you can hop up to the cooler stuff...
Good Luck! /forums/images/graemlins/thumb.gif
