My 98 12v was a total that had a cab fire and I replaced the cab on it. Wasn't a bad project except for the smell of burnt plastics, etc. Have you found a new cab? A 3rd gen will still be kinda hard to find as they haven't been out for a real long time. The best place I've found for dodge parts (specifically 3/4 and 1 ton diesels) is Davis Auto Salvage in Corbin, KY. Give Herald a call, hell set you up if he has anything, Usually gives you little stuff you mught need (like pieces of wiring harneses, interior bits an pieces). As far as the actual dissasembly and assembly goes there's nothing to sweat, There are a few main wiring harneses, everything on the fire wall can be taken off and laid in the engine compartment, don't have to break any fluid lines (except for heater/AC and winshield washer), the steering shaft comes off easily, you have the parking brake and the cab bolts underneath. Don't forget to do a thourough inspection around the cab to check for ground wires or anything else hidden that could break when you lift the cab. Most importantly though you should have fun, fixing wrecks gave me some of my best memories/lessons, and you can learn alot and better comprehend what the truck is by restoring your own vechicle that you would have missed if you just went out and bought it.
