Have to be careful what you recommend! a stock TJ Dana 44 is 3.07 long geared!Is this shop in Los Anchorage? Good shops will give multiple options and reasoning behind those options not tell you to stay off the interwebs. There are good resources up here both in person and online that will help you. For 33s there is no reason to do anything but regear and add a traction device up front. Assuming the rear is a Dana 35 that would be one place I would consider upgrading but there is no reason you cannot gear the 35 and run it while you save up. If it were mine I would keep an eye out for a stock Dana 44 if you plan on staying with 35s or less. They pop up from time to time for pretty decent prices usually you just have to be quick on the draw.
