Why list tools needed for parts the guy doesn't have? Even then they have to remove the skid.
Without those parts it's a breeze, and to my knowledge there is no difference in late-model landcruiser/LX vs early.
10&12mm for removing the skids, 14mm for pan drain, 3/8" square for oil filter housing drain plug, good toyota-specific filter housing wrench with the slots on the sides, not just the 14-(or whatever) sided hex, torque wrench capable of 9 ft-lb up to 30.
Don't forget to get pan drain gaskets, and when you use the filter housing drain spout put the drain plug oring into its groove on the spout before firmly pressing it into the filter housing. When done this way you won't spill much if any at all.
