its not that the stock steering setup won't work that big, but that the stock stuff is stamped steel and won't last long with a 33" tire or larger... bends easy
rustys has a good lookin kit out, as well as JCR offroad but the JCR kit involves drillin/reaming.
driveline you'll have to see, if you do a D44 or something at the same time then the pinion is 1" longer on the d44 than the d35 and that'll help but if you're jsut lifting then you may need to extend the D/S
edit: just read again see you have a factory d44 get someone to measure a MJ with the same driveline/bed length but a d35 and see if that shaft isnt a little bit longer, probly find someone who has one laying around if it is indeed longer
