you named just about everything that is recommend, will need new gears if you want it to have any power at all going up a hill. Will need new driveshafts at some point, mine went out after 5k miles of flat driving. Would not recommend going over 2.5" lift and 33"s unless your willing to dump some cash on other things. Ive had my 35's for about 10k miles now and love them, but did have to upgrade the gears and driveshaft to make it enjoyable.
I did run the 35's on it for about 5k miles without the gears and the 4.10 are just barrelly tolerable with a 6spd. Pulling anything, head wind and even small hills would bog the engine.
