Just remember...it's passenger side to driver side to loosen the viscous fan clutch
(i.e. clockwise if you're standing in front of the vehicle facing it). Ask me how I know: http://www.defendersource.com/forum/...ad.php?t=40545
But technically I don't *think* you need to remove the fan to do the belts, though it may make it easier. I replaced all of my belts at a later date, and just can't recall if I pulled the fan at that time (pretty sure I did not). The power steering belt was more of a bitch, and I actually ended up just pulling the bolts that hold the pulley on and slipping the entire pulley off to replace the belt (which is actually how many shops do it).
Just remember after some time on there you'll need to re-tension the belts after the seat/stretch.

As for the fan belt, do I loosen/unbolt the idler pulley?
Yes, as you lay underneath the truck you can look up at the idler pulley and you'll see the adjustment bolt on there, just loosen it and you'll be able to rotate the pulley enough to loosen & get the belt off.
