if your a mechanic you will have no problems at all doing it. Use a stumpy 14mm ratchet spanner on the top starter motor bolt and some rope to crack it loose, works every time when the box is hanging you should be able to run your hand along the top of the box, from the rear to the front, and undo the bolt with the tips of your fingers.
dont stress about the tranfer case hose, some vice grips and a thick rag and clamp it off. To be honest i have never had to bleed one and i have done about 40 0f these clutches. Never had a problem with the 4WD system not working after the clutch was changed.
If you have a trans jack it should only take you about 2 hours to change it over.
